Adam Peaty's new 100-metres breaststroke world record has been adjusted due to a problem with the timing mechanism, the European Swimming Federation has announced.
Peaty recorded a time of exactly 57 seconds on Saturday night but it will now go into the record books as 57.10 after organisers revealed a "configuration delay" of 0.10 seconds affecting the first nine races of the session.
In a statement the Federation (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."
The revised time means Peaty still broke his own previous world record mark of 57.13, set during his gold medal win at the Rio Olympics.
The statement added: "Upon thorough investigation it became apparent the starting mechanism had been incorrectly configured prior to the start of the session which resulted in all reported times being 0.10s faster due to a configuration delay of 0.10s.
"The LEN TSC, working with the timing system operators, carried out extensive tests to confirm this system configuration error and have, with the benefit of the necessary technical analysis, revised all recorded times for the first nine races during that session."
