  2. Medal ceremony

    Ben Proud stands on the World Championship podium, collects his gold medal with 'God Save the Queen" blaring and the Union flag behind him...

    He looks so.....


  3. 'It was a test of character'

    Siobhan-Marie O'Connor speaking to BBC Sport: "It's been touch and go whether I'd come. I didn't get what I wanted but I'm so glad I came. I've just realised how relentless sit its. Last year was the best year of training and this year has been far from ideal.

    "It's going to teach me a lot. It was a test of character. I knew I wasn't in the shape I wanted to be but I've made the team and you don't get opportunity very often."

    Siobhan-Marie O'Connor had to commit but she went out too hard.

    She had a great start but after taking a long break, she hasn't got the base to back it up.

  5. Post update

    Siobhan-Marie O'Connor was just a little too tired but the crowd have gone mad here as their girl just took the title.

    Hozzu is now a six-time World champion.

    The crowd have just absolutely deafened the commentators in the arena...

    Hozzu in lane 4, O'Connor in lane 6.

    And they are off....

  8. O'Connor's 'fantastic skills'

    Rebecca Adlington

    Double Olympic gold-medal winning swimmer

    Siobhan is such a racer. She loves it and has fantastic skills. She has one of the best starts in world. She pulled out of 100m breaststroke to concentrate on this event, so she can give it everything she's got.

  9. The main event...

    Katinka Hozzu

    Adam Peaty may be the big name in the pool for Great Britain tonight but for most of the Hungarians in the Duna Arena, there is only one person they are here to see.

    Ok two. But it is the same person...

    Katinka Hozzu - "The Iron Lady".

    Three-time Olympic and five-time World champion Hozzu is the star of these Championships she is basically the reason Budapest is host city.

    Expect the roof to come off when she enters the arena tonight...

    Hozzu is also the world record holder in the 100m, 200m and 400m individual medleys.

    In 2014, she became the first swimmer in history to earn over $1m in prize money.

    She is in lane four of the 200m individual medley tonight.

    GB's Rio 2016 silver medallist Siobhan-Marie O'Connor has a fight on her hands if she wants a place on the podium.

    What on earth are they putting in these men's meals back at the Team GB hotel?! They must have had some decent cereal this morning.

    We could have two British men on the podium here. They will take the best two lanes in the final.

  12. Scott wins second semi-final

    Men's 200m freestyle semi-finals

    Remarkable! Duncan Scott also finishes in first in his semi-final and he tops his team-mate James Guy's time!

    The Scotsman comes home in 1:45.16.

  13. Post update

    Men's 200m freestyle semi-finals

    Duncan Scott of Britain is up next trying to qualify for the men's 200m freestyle.

    He's in lane six and looking strong early doors...

    Mark Foster

    Former freestyle world swimming champion on BBC TV

    James Guy really is a showman. He is a big personality and he loves racing on these big stages.

    I think it was also a really measured, really controlled race.

  15. Guy wins semi-final

    Men's 200m freestyle semi-finals

    James Guy on BBC Two, after coming first in his 200m freestyle semi-final: "The plan was to be relaxed but go in hard. It felt great. I know what I'm doing in the race. In the 400m I was a bit all over the place but this felt good."

    I think James Guy has just realised he is in the form of his life.

    Men's 200m freestyle semi-finals

    James Guy was second at the 100m mark...and he comes home in first! He clocks a time of 1:45.18!

    A brilliant race from the defending champion.

    Off we...go!

  20. What can Guy do?

    Men's 200m freestyle semi-finals

    Rebecca Adlington

    Double Olympic gold-medal winning swimmer

    I think James and Adam Peaty have such a great relationship. They're room-mates and team-mates.

    As we saw in Rio, James just gets better throughout the week.
