Ant and Dec present the first of the Britain's Got Talent live semi-finals. This was the first time Britain's Got Talent aired in HD on ITV 1 HD.

It is decision time for the first eight Britain's Got Talent semi-finalists as the result of the public vote is announced. Only two acts will go through to Saturday's final for a chance to compete for the 100,000-pound prize and a slot to perform at the Royal Variety Performance.
