Olympic silver medallist Michael Jamieson is the latest star name to confirm his entry to the 2015 British Swimming Championships at London Aquatics Centre.
The 26-year old has won the 200m Breaststroke title at domestic level four times in the last five seasons including the past two years, while he has also reached the 100m Breaststroke podium at the past five British Champs.
The last time Jamieson failed to top the podium at a British Champs was 2012 - the last time the event was held in London - when he touched third in the 100m Breast and second over 200m.
Double Commonwealth silver medallist Lauren Quigley became the top female entry as she confirmed she will line up in five events.
The 19-year old Stockport Metro swimmer won her first British title with 100m Backstroke gold in 2013, then landed the 50m and 200m Back titles as well as 100m Back silver last year at Tollcross.
This year, Quigley will compete in the 50m, 100m and 200m Free and the 100m and 200m Back.
