but it's not because of anything he did. egyptjoin ghana in the quarter finals of the africa cup of nations after beating the black stars in their final group game. and tiger takes a step into the unknown. the world number 663 is back on a full schedule for the first usain bolt has been stripped of one of the nine olympic gold medals that made him unique among sprinters. it's the medal he won in the 4x100 metre relay at the beijing games in 2008. it's now emerged that one of his team—mates — nestor carter — tested positive for a banned stimulant after sa m ples were re—tested. it means bolt no longer holds the accolade of having won the triple—triple — as katie gornall reports. in a sport measured in fractions of a second, this was an astonishing feat of longevity. commentator: the triple triple! he's done it!

usain bolt‘s nine fold medals, at three different olympics, was unprecedented. now, through no fault of his own, that history has been tarnished. the reason lies with this man, nesta carter, bolt‘s team—mate in the relay at the 2008 beijing olympics. his start propelled jamaica both to gold and to a world record. but last year, carter's sample from these games was retested and today he was found guilty of doping. under the ioc rules, the whole team is now disqualified. it's an outcome that bolt has feared for some time. i asked him about it back in august in his hometown of kingston. at any point, if i lose one of my medals it'd be devastating and stressful, do you know what i mean? to know that, after all that hard work, this would happen. but i think the sport is in a really bad place now and the only place it can go right now is up. it must be hard as well because the triple triple is such a special achievement? it's very, very, very special, but we'll see. fingers crossed. sadly, whilst bolt stood clean, his rivals have fallen around him. justin gatlin has been banned twice

forfailing drugs tests. tyson gay has tested positive for an anabolic steroid and his fellow jamaican, asafa powell, has served a six—month ban. today, nesta carter was found to have taken the banned stimulant methylhexaneamine. ididn't i didn't rule out that he would not performed guilty. i am surprised, though. bolt will now have to hand back one of his precious medals, still he'll retire with his legacy intact. katie gornall, bbc news. there are three semi finals to look forward to at the australian open in melbourne on thursday, with both in the women's singles pitting a williams sister against a surprise unseeded opponent. venus is about to get under way against the giant—killing coco vanderweghe. while after that, serena takes on mirjana lucic—baroni, who's reached herfirst grand slam semi final since 1999 and following a troubled career. one day i will say a long, big story

wednesday brought with it a day of contrasts. we had sopme beautiful sunshine out to the west, a depicted by this weatherwatcher‘s picture. lucky you. but unfortunately for many across the south—east saw some stubborn fog which lingered all day and made it feel cold. this was fog, good slice of sunshine behind, thicker cloud up into the north—west. and that's going to prevent temperatures from falling below freezing here but elsewhere it is going to be another cold night. a bit more of a breeze so not quite as much fog around but in rural spots it could be a bitterly cold start to the day, with temperatures down as low as —5 degrees. and it could be a little foggy, particularly to higher ground, and there could be some ice on untreated surfaces, so that's certainly worth baring in mind, and in particularly through pavements. a lot of cloud around first thing in the morning. it's going to be potentially a cold start, but we're dragging in a breeze from the south—easterly direction. it has been a bitterly cold in europe and that is going to make it feel really quite chilly

if you are out and about through the day. always out towards the west, the winds will be strong but the temperatures not quite as low but nevetheless it is going to be a windy start to the day and the winds will continue to feature in western areas. a good slice of dry weather around. a fair amount of cloud. eventually, that south—easterly breeze might just allow for some sunshine to come across southern england. but your thermometer may well say around 1—4 degrees, which is disappointing enough, but add on the strength and that cold source of the wind — it going to feel much colder than that. as we move out of thursday towards friday, the wind direction changes subtly, from a southerly. and it is allowing these weatherfronts to push in from the atlantic, so we start off potentially cold with a little bit of frost, particularly the further north you are, but as we go through the day, these weather fronts will bring some showery outbreaks of rain and eventually some milder air in as well — 8—10 degrees into the south—west, 3—5 in sheltered eastern areas. that marks a change as we move towards the weekend. so something a little less cold but a little more more unsettled. with the weatherfront trying

to push in from the west. now, it looks as though we move out of saturday into sunday, there's a potential for more significant rain across southern england. a level of uncertainty just where that front is going to be sitting so keep watching the forecasts. that could bring some wet weather to the south. but double figures, slightly colder, but drier conditions up into the north. the cloud stays with us for the start of a new working week. but also double digits are likely to stay with us as well — 10 or 11 degrees the high. a very warm welcome to bbc news, broadcasting to our viewers in north america and around the globe. my name's mike embley. our top stories: putting pen to paper. donald trump signs an order to build his border wall and says mexico will end up paying. in his first interview since taking office, the president insists torture works, but there's unease in the intelligence community. chile suffers its worst wildfires in half a century, the us sends the world's biggest air tanker to help fight the flames. and mary tyler moore,
