BritBowl

BritBowl is the championship game of the British American Football Association Community Leagues, and formerly the British American Football League (BAFL) in the United Kingdom. It is the most prestigious of the league's three bowl games that constitute BritBowl Weekend. Only teams in the Premier Division of BAFL are eligible to compete in BritBowl. The lower divisions have their own championship games.

To mark its 20th anniversary, Roman numerals were introduced to identify the game. The 2006 Championship became known as BritBowl XX. The previous nineteen championship games were redesignated as BritBowl I to BritBowl XIX respectively.

Since BritBowl XX the winning team has been presented with the Boston Trophy. The current champions are London Warriors, who defeated London Blitz 36-15 in BritBowl XXX on 27 August 2016, recording their fourth consecutive BritBowl success in the process. BritBowl XXX was the 6th year in a row to feature both the London Blitz and the London Warriors.
