British swimming trials take place this weekend and all Olympic hopefuls will be put through their paces.

To guarantee a place at the Olympic Games, swimmers need to finish in the top two in their event and also make the 'A' standard time set by team GB.

It's also the first real test for the pool but some experts are already claiming fewer world records will be broken than in Beijing because an ergonomic suit, worn by 94% of gold medalists in Bejing, has been banned.
