VIDEO - A party is held at Liverpool Street Station to mark the banning of alcohol on public transport by London's new mayor Boris Johnson. Partygoers can be seen drinking, dancing, chanting and confronting police officers who try to keep order at the station. The mood seems to turn nasty as people start breaking equipment at the station and daubing graffiti. They can also be heard chanting 'Boris is a w****r.'
