Glasgow - British swimming great Adam Peaty's world record for the 100 metres breaststroke set on Saturday has been adjusted from 57 seconds to 57.10 seconds due to a problem with the timing mechanism, the European Swimming Federation announced on Sunday.

The 23-year-old showed a return to his old form after obliterating his rivals in Glasgow at the European Championships to improve on his old world mark of 57.13 seconds set on the way to winning Olympic gold at Rio 2016.
However, organisers revealed a "configuration delay" of 0.10 seconds affecting the first nine races of the session.
In a statement the European Swimming League (LEN) said: "The LEN.. have, with the benefit of the necessary technical analysis, revised all recorded times for the first nine races during that session."
