Britain's Adam Peaty has broken the men's 100 metres breast stroke world record with a time of 57.92 seconds at the London Aquatic Centre.

The 20-year-old from Uttoxeter's gold-winning time on Friday beat the previous record of 58.46 set by South African Cameron van der Burgh in the same venue at the 2012 Olympics.

A tweet from British Swimming's account read: "WORLD RECORD time for @adam_peaty he hits the wall in 57.92!!!!"

After becoming the first man in history to break through the 58-second barrier in the discipline, Peaty said: "I can't believe it, coming in earlier I thought I could get a really good time, maybe a 58.5.

"Before that race I just thought I've done all the training for a 57, and it all paid off in the end.

"The crowd were great and they really carried me home at the end, because that was a hell of a pain train. There must be something in that lane four when it really matters."

Scotland's Ross Murdoch fought hard but was left trailing in Peaty's wake with a time of 59.12 - still inside the World Championship qualification standard - while James Wilby of Loughborough took bronze with a 1:00.31.

Ben Proud topped the podium in the men's 50m freestyle by coming home in 21.99, with his fellow Plymouth swimmer Thomas Fannon taking silver in 22.48 from Andrew Weatheritt (22.50).

In the women's competition, Fran Halsall stormed to victory in the open 50m freestyle.

The 25-year-old claimed her 10th consecutive title with a time of 24.37 and said afterwards: "It's pretty good to be able to come in 10 years in a row and be the best in Britain.

"I didn't have the ideal preparation coming into this meet, I got sent home from the World Championships in December and it took a lot longer than expected to get back into full training.

"Last year I went a 24.5 at this meet then on to a 23.9 in the summer, so to come here and already be two tenths up on that is a great sign."

Lauren Quigley of Stockport Metro hit 25.22 for silver ahead of Rebecca Guy, who clocked in at 25.49.

In the morning Rachael Kelly had defended her British Championship title with a time of 57.72 in the open 100m butterfly final.

Jemma Lowe (58.07) collected silver with Bath team-mate Siobhan-Marie O'Connor third thanks to a 58.37.
