negligence manslaughter. constance marten and her partner, mark gordon, who's a convicted sex offender, were found by police in brighton on monday after a member of the public reported seeing them. our home affairs correspondent daniel sandford has the latest. working their way slowly through allotments in north brighton, police officers from london searching for a missing baby. every shed and greenhouse was being checked with temperatures close to zero. 0fficers looking for an infant, who was born less than two months ago. the baby's parents, constance martin and mark gordon, were arrested last night after a police hunt that began injanuary. they are now being held on suspicion of gross negligence, manslaughter. they had been in this convenience store and were spotted by a member of the public who called 999. they were arrested just moments after this cctv camera caught them walking along a road that leads to the allotments and a golf course and the south downs beyond.

but there was no sign of the baby. as time progresses, as the weather is closing tonight, as it was last night, in terms of the cold and the coldness and the impact that would have on a baby, clearly the risk is getting higher and we have to be open to the fact that this may not end in the way we would like, but we need to remain hopeful. constance martin comes from a hugely wealthy family growing up in this country house in dorset. her father was so close to the royal family that in the 1970s he held the ceremonial role of third paige of honour to the late queen. injanuary, he made this appeal to his daughter. darling constance, even though we remain estranged at the moment, i stand by, as i have always done, and as the family has always done, to do whatever is necessary for your safe return to us. constance martin became estranged

from herfamily in 2016, when she met mark gordon. he was convicted of rape in the united states, aged just 1a, and served 20 years in prison. police believe the baby was born in the back of a car in earlyjanuary. the couple came onto the police's radar onjanuary 05, when their car caught fire on the m61 near bolton. from there the pair took a taxi to liverpool and another to harwich, arriving there on the morning of the 6th of january. by lunchtime on the 7th of january, they were in east london where they bought a tent from argos and abandoned their pushchair. they were then yet more taxi journeys, including a final one to the port of newhaven. since then they'd evaded detection untiljust before 9:30 last night when a member of the public saw them and dialled 999. while detectives still hope the baby is alive, perhaps being looked after by someone else, they're becoming increasingly concerned, and constance martin's father has said that while he's relieved that she's been found, but he is worried

about the missing baby. the us supreme court has heard arguments over the legitimacy of president biden�*s plan to cancel student debt for around a0 million americans. last year the president promised to cancel $430 billion worth of student loans after the covid pandemic under a federal law known as the heroes act, which allows debt relief in national emergencies. six republican—controlled states have challenged the plan in the supreme court, arguing mr biden is exceeding his powers. tara grove, a law professor at the university of texas school of law, told us why the case has ended up in the us supreme court. these are both challenges to the student debt programme, so one brought by several states, as you noted at the beginning. the other is brought by two private individuals, both before the supreme court. the legal questions are whether the court can actually hear the committees,

whether it has jurisdiction, whether the states who were challenging or the individuals who are injured by the programme and the second question is does the heroes act actually allow the biden administration to get rid of student debt. what is the crux of the republicans' argument against biden�*s debt relief plan? the crux on their merits is that the heroes act does not specifically say that the government can forgive it allows the secretariat of education to waive or modify things and they say it does not allow them to completely erase the student loan debt. they also rely on a very recent supreme court law called the major questions doctrine and this idea is basically what states are arguing

or what the individuals for me, the ideal outcome would be that it would be states are individuals if the courtjust reads the statute as is, the court could uphold the programme and it does seem like waiving or modifying the requirement of the student loan programme. but if the court applies this major questions doctrine, i think the biden administration will lose the case. can you explain the scale of the student loan crisis in america? so, the amount of loans that would be forgiven is on the scale of $400 billion.

to put that in perspective, the government is talking about forgiving either 10,000 or 20,000 dollars per person stay with us on bbc news. in thailand. sideways and downwards. onto her side. the hydrogen bomb.

after two trains collide in greece. nigeria's governing party candidate, bola tinubu, is declared the winner of saturday's disputed presidential election. the british prime minister has been in belfast, trying to build support for his new deal with the european union on trading arrangements for northern ireland. rishi sunak has been speaking to sinn fein, the alliance party, and — most crucially — the democratic unionists or dup, whose support is vital if the political deadlock in northern ireland is to be broken. 0ur ireland correspondent emma vardy has more details. with the deal done, today was the day for the hard sell to ordinary consumers of northern ireland and to business. we managed to... at a coca—cola factory in lisbon, the prime minister wanted to emphasise the advantages of being able to sell both to the uk and into europe. that is the prize that is on offer because if we get this right, if we get this framework implemented, if we get the executive back up and running here,

northern ireland is in the unbelievably special position, unique position in the entire world, european continent, in having privileged access notjust to the uk home market, which is enormous, fifth biggest in the world, but also the european union single market. many businesses have welcomed the deal, which cuts down the barriers they had faced bringing goods over the irish sea. products staying in northern ireland will no longer need as much paperwork, but some, like this coffee company, are still working out whether they'll qualify for the new green lanes. most of what we bring in we sell in northern ireland. however, we also sell into the south. that seems to be trying to say we want to make this easier but have no detail yet, so we don't really know. we have a number of manufacturers who are no longer supplying us, so we might see if we can get some of those back. the deal also affects what products customers can buy in their weekly shop, because the eu's ban on certain goods like chilled meats

entering northern ireland has been scrapped. so, for shoppers, it means that things like sausages from britain or haggis from scotland can be sold on northern ireland's shelves and for parcels being sent from britain to northern ireland, there will be no need for customs declarations. i think it's good. i didn't agree with brexit in the first place, so ijust want to see things back and running smoothly. i'm delighted that there is some progress and some common sense. 0nline shoppers should also face less complications. i had furniture on order that i've been waiting for for ages. we're no longer endeavouring to northern ireland. because you're ordering from britain. it shouldn't be like that. and for pets travelling from great britain to northern ireland, under the old rules, they would have needed to show health certificates and proof of vaccination, but now only need to show they've been microchipped as long as they're not travelling on to the irish republic.

but the big political jeopardy remains — a government can only be restored if the dup drop its opposition to the brexit arrangements and rejoin the power—sharing assembly. and for them, the jury's still out. we will take our time collectively to consider what is on the table to examine it, both in legal and economic terms. where is the potential in this, as you say? what are the opportunities? but are there downsides? but many businesses want to see the return of a stable government, so pressure on the dup may increase. emma vardy, bbc news, belfast. the us house foreign affairs committee is to debate whether to allow the complete ban of the chinese—owned app tiktok. the app is currently used by more than 100 million americans. the white house has already ordered government agencies to wipe tiktok 0ff federal devices within 30 days. and it's notjust the us. the european parliament has also banned the video—sharing app from staff phones citing security reasons,

as has canada. but china has hit out at the us. and this is what a government spokesperson had to say. earlier, i spoke to reuters journalist david shepardson who has been following the developments on capitol hill. this dates back to 2020 when the then president trump tried to ban the app and over the last three years the concerns that people within us government, both republicans and democrats, about what china could do with the data, those 100 million americans you referenced, if tiktok turned that data over. tiktok says it has spent over $1.5 billion to put in place this data security programme to protect the data of us users and to wall that off from any access to china and for more than two years there's been negotiations between the national security body of the us government and tiktok to reach an agreement on a data protection mandate but that hasn't been resolved and as these talks have gone on, some democrats in congress have pushed for a complete ban rather than waiting for these

negotiations to end. you mentioned there pushing for a complete ban, do you think this could be a possibility? could this actually happen? anything is possible but at this point, it will at minimum take a lot of uphill work to get that done. first you would need a majority in the house and since it is not clear yet if democrats will be on board today at a hearing, the democrats say this bill is not ready, they want more negotiations, more talks and then on the senate side you need many democrats to join as well and the white house to take part, to agree to it and so i think there would have to be a lot more discussions. it's hard for congress to get hardly anything done, i think it is true that there is no consensus and washington

to ban the app for the hundred million americans you are talking about. this could happen down the road but at this point it seems like the most likely scenario is there will be a lot of discussions and a wait and see attitude until the administration can determine if they can reach an agreement that is satisfactory and resolves the national concerns. will this have any impact on everyday americans who use the app? not now, not in terms of the government ban on devices that government employees do and there won't be any impact unless congress actually did it and that would be a significant time off if in fact that were to happen. david shepardson speaking to me a little earlier. pangolins are one of the most sought after animals on earth. they're mostly wanted for their meat and their scales, which can be used in traditional chinese medicine. there's been a global ban

of pangolin, and all of them are on the so—called red list of endangered species at risk of extinction. their meat is regarded as a delicacy in parts of asia, and their skills are said to have powerful medicinal qualities. bess and buster will be used airports, ports and along thailand's road network, and this is a lifetime commitment for the pair of them. they'll have a working life of about seven to eight years, and then they'll be retired and cared for in thailand. so, yeah, we're going to sunnier climes. the world wildlife fund says that the pangolin is the most trafficked memo in the world. if all goes according to plan, bess and buster would have something to say about that. tim allman, bbc news. sea cucumbers are arguably the ocean's unsung heroes. they live on the ocean floor, and, yes, they look like soggy sausages, but they help to keep the waters clean. and they're also a popular dish in parts of asia, which means their numbers have been declining. one solution is to actively farm the cucumbers cucumbers. the bbc world service went

and ambulance staff are at the scene. the passenger train had departed from thessaloniki in the evening. good morning. not a lot happening in any great hurry in terms of the weather across the uk in the days ahead. a big area of high pressure centred to the north of scotland has been with us so far this week and it stays with us right the way too into the weekend. you can see it wobbles about a bit in the next few days. but to the changes really that that will bring about are going to be very subtle in the next couple of days, very much like it's been just start the week. there'll be a lot of cloud across the uk, but it will bear very little in the way of rain. it's the wind directions, if anything, that will shift about. and that could just bring about some changes where we see the showers. a northeasterly, again this wednesday favours the northeast of england, parts of the midlands, maybe south wales picking up some showers, a few for east anglia to the far

south east of england, maybe a bit more brightness than we saw on tuesday. again, some decent sunshine, i think for western scotland. temperatures on the thermometer, 8, 9 degrees. but in that northeasterly wind, it's going to feel closer to five or six. plenty of cloud drifting around again overnight, wednesday into thursday, perhaps the skies becoming a little clearer towards the southeast across southern counties of england, greater chance of catching a frost here and also again, clearer skies for western scotland, allowing it to turn chillier. but any breaks where we've got some shelter could mean we catch a frost for first thing on thursday. subtle change for thursday. well, there's the high picture. doesn't look too different, does it? but those ice bars are further apart. further apart, they get the lighter our winds become. and lighter winds for us on thursday may mean itjust feels slightly less chilly. so our temperatures will feel closer to the figures that we'd read on the thermometer. feeling around the nine or ten degree mark is an improvement by three or four degrees really from earlier in the week. still a lot of cloud drifting around, perhaps a little more in the way of sunshine on thursday, friday into saturday. the high wriggles a little bit further westwards, though. and look how those parallel lines start to track

from north to south. that's the indicator that towards the end of the week and into the weekend, we could well be pulling in some arctic air. so, yes, it's felt chilly with the breeze off the north sea recently, but come the weekend, we could be pulling in some much colder air. and later on in the weekend, into the start of next week, signs it might become a little bit more unsettled as well. so there's just the possibility of something a little bit more wintry in our outlook.
