Carlin and Willmott pull out of World Championships

Aimee Willmott will also not be joining the British swimming team in Hungary, as she was unable to fully recover in time from an ongoing injury.

Carlin had been taking a rest following her successful Rio 2016 Olympic Games, where she picked up silver in both the 400m and 800m freestyle, for her first medals at Olympic level.

But a combination of minor illness and injury has restricted her return to the pool, with the two-time World Championship medallist unable to add to her tally this time around.

Willmott meanwhile has had a knee injury to deal with, choosing to use the summer to get herself back in top condition as opposed to rushing back into the pool.

Like Carlin, the 24-year-old has plenty of silverware to boast, with two medals from the Glasgow 2014 Commonwealth Games to add to a plethora of European honours.

But despite the disappointing news, British Swimming head coach Bill Furniss believes the two have made the right decision given what the rest of their careers could hold.

"Both swimmers are a loss to the team but we respect their decisions which we believe will have a positive impact on their long-term futures," he told British Swimming.

"I'm disappointed for Jazz and Aimee and it is a loss to the team but we will have lots of athletes fully prepared for the World Championships and we're looking forward to it.

"Jazz had a long rest after last year's Olympics Games, which she needed to do. Since then she has been working hard, despite minor illness and injury, to get herself back into her best competitive shape but feels she isn't going to be able to get there in time for the World Championships.

"Aimee will be taking a longer break this summer in order to fully recover from injury, and then work towards being in the best shape possible at the start of next season."
