Back for its second year, the Sketch Off competition is open to any sketch groups and character acts currently performing in the UK, as Leicester Square Theatre search for the country's most exciting sketch writers and performers. Following on from Heats, the top qualifiers from the semi-finals will compete in the grand final in Leicester Square Theatre's Main House for the £500 prize and their own comedy showcase. Who will emerge victorious? You'll have to get tickets to find out. Over 14s only.
