Seven added to Team GB
The British Olympic Association have confirmed the addition of a further seven swimmers to Team GB for London 2012.
The move follows the British Gas ASA National Championships which concluded in Sheffield.
The additions bring the total number of Team GB swimmers who will compete at the Aquatics Centre to 44.
David Carry (400 metres freestyle, 4x200m freestyle relay) is the oldest member of the team at 30, Marco Loughran (200m backstroke), Chris Walker-Hebborn (100m & 200m backstroke) booked their slots along with Grant Turner, who was added to the 4x100m freestyle relay.
Antony James will compete in the 100m butterfly alongside Michael Rock, who had already qualified, with the pair battling it out for the butterfly slot in the medley relay.
At 16 Siobhan-Marie O'Connor is the baby of the squad after qualifying in the 100m breaststroke while Florida-based Steph Proud will contest the 200m backstroke.
There are additional events for five swimmers who had already qualified at the first trials at the Aquatics Centre in March.
Double Olympic champion Rebecca Adlington has been added to the 4x200m freestyle relay squad, former Commonwealth champion Caitlin McClatchey joins Rebecca Turner in the individual 200m freestyle as well as the sprint relay.
Adam Brown will take on the 50m freestyle, despite not having done the required FINA A time in either Sheffield or London but he qualifies through virtue of having achieved that at last year's World Championships and had already been selected for the 4x100m freestyle relay.
Ieuan Lloyd will compete in the individual 200m freestyle after already booking his place on the 4x200m relay while world finalist Michael Jamieson, already on the team in the 200m breaststroke, will double up in the 100m after Daniel Sliwinski was forced to withdraw through injury earlier this month.
Team GB chef de mission Andy Hunt said: "It is exciting to confirm a total of 44 very talented and ambitious swimmers to Team GB for the London 2012 Olympic Games.
"This once again demonstrates the remarkable strength and depth of British talent that has been developed within the sport of swimming.
"Team GB enjoys a proud tradition in Olympic swimming competition and I'm sure the class of 2012 will produce many memorable moments in the fantastic Aquatics Centre this summer."
Michael Scott, Team GB swimming team leader and British Swimming national performance director said: "With 44 swimmers on the team, we have seen around a 20% increase since Beijing.
"More pleasing though is the quality of the swimmers who have been selected and the progress that has been made since the March selection trials.
"I feel that we are fielding our biggest and best British Olympic swimming team and from talking to the swimmers and staff, they are relishing the opportunity to compete in front of a home crowd in 33 days time."
