Britain have named their 40-strong squad for next month's Fina World Swimming Championships in Shanghai.

Double-Olympic champion Rebecca Adlington and Commonwealth champion Fran Halsall will lead the women.

Double-Commonwealth gold medallist James Goddard and world champion Liam Tancock head the men's contingent.

British Swimming national performance director Michael Scott described the team as "one of the most competitive British teams ever assembled".

Scott added: "There will be some big challenges ahead this summer - but the squad has real talent and strength and is best placed to overcome these."

"It's a healthy mix of experienced performers on the world stage as well as a group of exciting youngsters who will be looking to establish themselves on the team."

The team also features a group of athletes who have qualified for their first senior national team. The likes of Siobhan-Marie O'Connor, Molly Renshaw, Joshua Walsh and Jak Scott put themselves onto the team with impressive performances at last week's ASA Championships in Sheffield.

"Any World Championships is an important event and marker but the one prior to an Olympic year is a key measure that gives us a strong indication of where we are in our journey to the London 2012 Olympics," stated Scott.

The squad are set to finalise their preparations at a holding camp in Osaka, Japan before arriving in Shanghai.
