British runner Josh Kerr has broken the world record for running a mile - which has stood for 27 years.
The Scottish athlete completed four laps in the Diamond League meeting at the London Stadium, in the capital's Olympic Park.
A capacity crowd of bout 60,000 saw him shave half a second off the previous best, set in 1999 by Moroccan Hicham El Guerrouj.
Kerr, the Olympic silver medallist in the 1500m, crossed the line in front of a rapturous home in 3 mins 42.66 secs.
He had been targeting the record as part of what he called "Project 222" - the number of seconds he needed to hit to beat the record.
His previous best was 3 mins 45.34.
Kerr ran in a specially designed black suit and running spikes by the running company Brooks.
His win means the mile record is back in British hands after Roger Bannister famously became the first person to run under four minutes in 1954.
