acrobatics, the commonwealth games. acrobatics, they were just out of this world. she takes gold! brilliant. we promised you the masters. let's join eilidh barbour. the world's best are peaking perfectly for the first major of the season. perfectly for the first major of the season. tiger is back, he's fit and he's informed. ken brown alongside me here. always a buzz around this place, but walking around augusta national this week, it has been ramped right up. it has been amazing. on the practice days, the crowds here in their droves. exciting to see tiger back. only playing five times since coming back, each week getting better. last time out, he looked like winning. he still has the power and is putting nicely. tiger has a really good

chance this week, no doubt about it. playing with mikkelsen, plenty of people watching. he has the vibe of the tournament every time he plays. we heard a few roars around augusta with tighe encores. in terms of europeans, the europeans have won the last two masters. the challenge this year is led by rory mcilroy, going for the grand slam of majors and his first green jacket. could this be the year? when rory started to find form, i thought this would be his first major, and he was close in 2011. he has the perfect game for augusta, hitting further than ever, with the big, high draw. he putted beautifully in florida, so if the weather is right for tiger and it doesn't get too breezy, sorry, rory, he has a really good chance, no doubt about it. he has already won the open, the us open, the us pga, and the masters is the final leg of

the grand slam. only five other players have managed to do that, and he would be in elite company. really exciting week. you can follow it on the bbc. it starts tonight at quarter past 11. we have highlights of the first two days before we are light and uninterrupted over the weekend. who will get the green jacket draped across their shoulders on sunday night? we can't wait to get under way here at augusta national. that's all from sportsday. we'll have more throughout the evening. russia has lost a vote at a meeting of the international chemical weapons regulator at the hague, calling for a fresh inquiry into the salisbury nerve agent attack. russia has demanded an emergency meeting of the un security council to discuss the uk allegations. meanwhile, boris johnson has accused jeremy corbyn of siding with the russian spin machine after the labour leader said the foreign secretary had exaggerated a claim that moscow was behind the attack. our diplomatic correspondent james landale is here. the foreign secretary there really

on the attack againstjeremy corbyn, but the foreign office itself is facing some embarrassment having somewhat overstepped mart in some tweets it has been making. what's happened is the british government has gone into a muddle. the basis of its assessment that it was highly likely that russia was responsible for the nerve agent attack in salisbury was always based on a bit of science and a bit of intelligence. the science saying this stuff is not a jot, a nerve agent from russia, and the intelligent agent saying the russians have stockpiles and a programme, an overt state and an assassination scheme, and in all likelihood, russia was behind it. what has happened is the head of the

military laboratory has said it is not theirjob to say to is the russians. the problem is that, even though what he said was technically correct, the foreign secretary in previous interviews has suggested that, perhaps porton down had pointed the finger at rochon when it hadn't. there was a similar foreign office to eat suggesting that porton down had suggested russia was behind it. the foreign office have now deleted that inaccurate tweet. what it has done is muddied the waters and given russia an opportunity to come back and say, look, there is fresh doubts over the british evidence. that is the claim. they have brought that claim to the chemical watchdog, and are attempting to have another second joint investigation, which has been rejected. in other words, the diplomatic row about this carries on. james, many thanks for that. jerry smith is a former weapons inspector at the organisation for the prohibition of chemical weapons and i can now

speak to him via webcam. thanks very much indeed forjoining us. thanks very much indeed forjoining us. is this body now, which is carrying out its own investigation, going to be able to establish where another —— the novichok has come from? i suspect not. the investigation that they are leading on is to take the image serial —— ta ke on is to take the image serial —— take the material from the uk and ta ke take the material from the uk and take environmental samples at the location in salisbury. they will then split it, and i understand it will be sent out to a number of opc w credited laboratories around the world, which will do their science to identify it. the laboratories will be looking at the samples from a scientific perspective. they will come back with answers on what they

believe the material to be. but i think it's more of a challenge for them to actually say either who manufactured it or who used it. even if they identify very closely exactly what the substance is, are there other countries beyond russia that could have been responsible? well, i suppose that is the question. when the identification of this novichok family came out in the early 90 ‘s, one would imagine that countries that were perhaps facing soviet or russian forces would have considered... would have done a risk assessment and determine whether they believed, a, that the whistle—blower was valid in his assessment, and if they believe that, they would have looked at

analysis to ensure that their detection and detection equipment was good enough. the best way that you can look at that and make sure that your equipment is protective is to manufacture small amounts yourself, and trial it. that would be perfectly accidental under the chemical weapons convention, so nothing has been broken. but conceivably, it would be a struggle to see that only russia could manufacture this type of material. now, when the investigation is carried out, and i had to ask you to keep this brief, will they point to how it may have been delivered, how the attack was carried out? again, i suspect not. what the opcw has been asked to do is verify the chemical analysis. i don't think at this stage there has been a question of conducting an investigation, per se, it is more chemical analysis and confirmation or otherwise of what porton down has found out. however

conclusively they identify the chemical, the diplomatic row is going to continue? yeah, i think so. yeah, i guess the uk has got that information either from intelligence sources or police investigative sources or police investigative sources or police investigative sources or other, pointing towards identification. that's the reason the uk has pointed towards russia. but that's not the remit of the opcw. thank you very much indeed for talking to us. matt taylor has the weather. good evening. the good news is that the sunny skies we saw in scotland through this afternoon will be with more of us for tomorrow. to get there, southern scotland, northern ireland, rain and hill snow to take through the first part of the night. still a few showers elsewhere through england and wales, all becoming confined toward east anglia later on. a legacy of cloud left over east anglia and the south—east into the morning, so temperatures will hold up here. quite breezy, though, but for the north and west, the skies cleared. could get down to around —6 or —7 in parts of scotland

and northern ireland. but lovely, crisp frosty start here, and lots of sunshine developing. even in east anglia and the south—east, the morning cloud will clear away. a few isolated wintry showers in northern scotland. for most of you tomorrow, it will be a very nice day. it's going to warm up a little bit after that chilly start. strong sunshine overhead, light winds, feeling pleasant with temperatures of around 9—13 degrees for many. sunshine turns hazy in the west later on, all ahead of a weather front that will bring rain to western areas on friday, but further east, southerly winds will bring more sunshine and a bit more warmth. you're watching beyond one hundred days. china hits back fast and hard against american tariffs. donald trump says it's not a trade war — the financial markets aren't so sure. beijing makes it clear it's not to be messed with — if its exports are hurt it will fight back. russia convenes a chemical weapons meeting in the hague — but britain says it's just trying to escape blame for salisbury. also on the programme.
