Billy Brit is a puppet character who has been used in YouTube videos by the youth wing of the British National Party.
The "Heroes" video was criticised by Hari Kunzru of The Guardian. An episode of Have I Got News for You played a clip containing the Boudicca verse, prompting Stuart Maconie to jokingly comment "Pixar have gone really downhill, haven't they?".
The puppet itself was not commissioned by the BNP but was, in fact, a standard puppet bought off-the-shelf.
