right, the suction's blocked. suction's blocked? yes. then the flow begins. it's dropping, mate, it is dropping. the way is now clear, but the tunnel is too low to stand in, so chris has to hunch and shuffle in the dark. at last he can do what he was sent for, hack away at a congealed mass of fat, tampons, wipes and condoms. it's blocking most of the sewer. pressure hoses can't be used because the brickwork is damaged, so it's one shovel stroke at a time, and it's hard to believe this is happening in 21st century britain. while they're working, the pipe reaching the surface twitches as each lump of fat passes through, but the work can't go on for long, it's just too hard. look at how tired chris is and what he's covered in. it's horrible down there, mate. there's so much fat everywhere, do you know what i mean? even upstream, upstream you can see

20 meters that way it's fat. do you know what i mean, it's solid. and this is a piece of the fatberg, a compacted mass of oil, fat and grease. it's rock solid and, as you'd expect, it smells a bit like a blocked toilet and rotting meat, and the real problem here is that the only way to get it out is by hand. this is a national problem affecting countless sewers and it's getting worse. since the victorians built the network, the population has grown and diets have changed. fried food and takeaways mean more grease is flowing into drains. there are devices to trap fats, but few places have them. we've visited over 700 food service establishments, takeaways, restau ra nts to really u ndersta nd what they're doing with the fats, oils and greases that they pour down the sink, and we found that over 90%, around 90%, have no type of fat removal to trap that fat and stop it

going into the sewers. the fat is hard to break apart, it'll be turned into fuel. but as one of the sewer teams recovers, the hope has to be that less fat will end up underground in the first place. david shukman, bbc news. newsnight is coming up on bbc two, here's emily maitlis. tonight, that full emma thompson interview with her views on harvey weinstein and endemic misogyny in hollywood. join me now on bbc two. that's newsnight with emily. welcome to sports day. tonight, scotla nd welcome to sports day. tonight, scotland starting the search father a new football manager. it follows the end of gordon strang and he is reign after scotland's failure to make the play—offs for next year's world cup in russia. british swimming says sorry for what a report found to be a climate of

fear. thank you forjoining us on a night when scottish football is really looking back on the reign of gordon strachan who today left his job as manager. as the search now starts for his successor, former players have said it feels a shame he has left by mutual consent because he says there were positives signs, despite the failure to qualify for next yea r‘s world cup despite the failure to qualify for next year's world cup in russia. i spoke to chris tonight. first of all, i wasn't shocked because i felt i wouldn't be surprised if gordon walked. i don't know exactly what went on today. you read the sfa have said they're not going to renew his contract but you are disappointed because i felt as a country we were starting to get somewhere. now we

can go back to square one. you look at the last year or so, there was that unbeaten run, that almost so nearly a victory against england. it was looking so good. it was only at the final hurdle that it wasn't quite enough. yeah. you listen to people saying it's the same old story and same old hard luck story for scotland. i am story and same old hard luck story for scotland. iam not story and same old hard luck story for scotland. i am not buying it. for me i think if it's happened once, you can say yeah it's unlucky but it's been 20 years without getting to a major competition it's not unlucky. there's something wrong in scottish football. something not working. i think when you look, we continuously give managers a campaign ortwo continuously give managers a campaign or two campaigns, why don't we go long—term? let them build on something. i think you need to look at the reaction coming out of the players tonight to realise what gordon really meant to them. what do you think gordon strachan‘s legacy will be in his nearly five years in charge? a better place than when he took over? yes, no doubt about it.

at the start of the campaign there was people calling for his head then. i think that's behind gordon's decision to go as well. no doubt scotla nd decision to go as well. no doubt scotland were on the right tracks recently but you won't have forgot what people were saying not that long ago, he will be dispointed with that, disappointed with not least not getting to the play—offs but i think he can leave with his head held high. the performances recently. indeed encouraging signs. who would you like to take over, do you want it to be another scottish manager or even look at an englishman? i think you would love a scottish manager who could replace gordon straightaway. yeah, go and do it because we have not qualified. that's not the case. there is obviously names that will come out. malcolm mackay is already in the building, i have seen his name linked. david moyes. he is somebody his club career has maybe took a dent the last few years, no doubt

there is an excellent manager in there. you would rather have a scottish guy there leading from the front. the thoughts there of the former scotland striker kris boyd. elsewhere, after chelsea's success in the women's champions league last night manchester city cruised through to the round of 16 after beating the austrian side six nil on ago agree grate. it was a dramatic night for glasgow. at one point they we re night for glasgow. at one point they were 4—0 down on aggregate. but they fought back to bring the scores tied over the two legs. they were equal. then they had this penalty in the closing stages to win the tie. but agonisingly it hit the post. so the visitors went through on away goals. british swimming has apologised to some of its paralympic athletes after it was found a former head coach created what was called a climate of fear. an independent investigation into complaints of bullying from 13 swimmers found that

an unnamed member of staff understood to be rob greenwood, had been communicating with athletes in an abusive manner as well as using derogatory terms to describe athletes. greenwood led the team to 47 medals at the rio paralympics last year and left his job before the inquiry started. contacted by the inquiry started. contacted by the bbc, he has declined to comment. carson russell, the father of hannah russell, who won two golds in rio was one of the swimmers and families who received today's apology. you have to be careful of sort of throwing sticks and just highlighting problems all the time. the most important thing is to find solutions. there has been some issues but the most important thing moving forward is there are some solutions, there are recommendations. but the caveat to thatis recommendations. but the caveat to that is that those have to be delivered. now the european rugby union season started tonight. it hasn't begun too well for gloucester. they were in france. they found themselves 14—0 down at

the break. they made the final of this competition last season. they did rally in the second a little. a late kick and a try earned gloucester a losing bonus point but it finished 27—21. ben stokes management company have released a statement saying the england all—rounder will make public his full explanation and evidence when the time is right. he was arrested under suspicion of causing actual bodily harm after a brawl outside a nightclub in bristol last month. no charges have yet been brought by the police. while the investigation is ongoing he will play no part in the ashes tour which sta rts play no part in the ashes tour which starts this month. joanna conta's form has ended out on her missing the end of final. she is unable to qualify for the singapore event. and criminal proceedings have opened

against the paris st germain chairman by swiss prosecutors. the proceedings are connected to an ongoing investigation into former fifa secretary general and relate to the sale of world cup tv rights to be in sport. it is described as a once ina be in sport. it is described as a once in a generation transformation of pe across primary schools in england. this year the government announced it would be doubling the amount of money it gives to schools to spend solely on physical education and sport and they'll start to receive the first instalment at the end of this month. we sent our reporter to a school in manchester to see the impact it's already having. pe and sport has changed down the yea rs pe and sport has changed down the years from military drill, to 21st century activities. an increase in funding means thousands of schools across england can do more of this. an extra ringfenced pot of money to

increase the quality, quantity and impact of pe and sport. this is a once ina impact of pe and sport. this is a once in a generation opportunity. we know that through an active curriculum within physical education and other classroom lessons healthy children do well in school. what sort of numbers are we talking about? pe and sport funding used to be £160 million. last year the then chancellor announced that figure would be doubling to £320 million. 0n would be doubling to £320 million. on average, that works out at nearly £19,000 per school. under government guidelines schools can do things like bring in external coaches, introduce new sports and buy equipment or run competitions. here at this primary in manchester they're spending that money on their own year of cycling. every child is going to get a five—week coaching block of cycling as well as an off site experience at either the velodrome or bmx track and we are going to be investing in new bikes

for the children, coaching for staff so for the children, coaching for staff so it's a long—term sustainable project. it keeps me fit and healthy. it's great to have everyone involved. so the kids are enjoying it but what about after 2020? there is no commitment the investment will continue. are the brakes about to be applied? the important thing now is to work with schools is making sure that it's a sustainable legacy for this investment. and that we don't waste it away because the likelihood is we are not going to get this money into schools again and we need to make the most of what we have got. how do we know schools will spend this extra cash on sports and in the other subjects? they are required to publish spending on their websites and 0fsted hold them accountable. whatever happens, children over the next few years are set to benefit, it's better than being in the classroom, right?m gets you very fit and it's nothing boring like maths or geography. it's a lwa ys boring like maths or geography. it's always fun. it's hard to argue with that.

wouldn't it be good to be starting primary school again in the playground. that's all from sportsday. coming up don't go away, it's the papers. see you soon. hello and welcome to our look ahead to what the papers will be bringing us tomorrow. with me are hugh muir, columnist of the guardian and laura perrins, co—editor of the conservative woman. tomorrow's front pages now. theresa may faces a battle to get her brexit legislation through parliament, that's according to the daily telegraph. the guardian pictures a family who

have been released after being held hostage by militants linked to the taliban for five years. the daily mail claims there are calls for the chancellor to be sacked for being too negative about brexit. the metro focuses on the allegations against disgraced film producer harvey weinstein. they say the met police is investigating him over an alleged assault. the sun also focuses on this story featuring myleene klass‘s claim. vietnamese children rescued from traffickers and placed in council care are disappearing, possibly back into the hands of their traffickers, reveals the time. the express warns that the uk may be battered by a hurricane 30 years on from the great storm of 1987. the financial times leads

with donald trump's attempts to weaken 0bamaair and hsbc‘s choice of new ceo. saying the eu bill could be in trouble because of back bench rebellion. looks like things are unravelling for theresa may, facing real difficulty with the eu withdrawal bill. i think it was the report that was scheduled for this week but it has been withdrawn because of a possible rebellion over a number of amendments, because of a possible rebellion over a number ofamendments, including the henry viii powers which a lot of mps have difficulty with in terms of allowing ministers to have so much legislative power without parliament scrutiny. the other issue,

interesting issue, is right at the end of the report where it says ministers are increasingly convinced that mrsmay will soon reshuffle her cabinet to restore her authority. the tory infighting is continuing and it's
