Are Greek police 'colluding' with far-right Golden Dawn?

Greece's far-right party, Golden Dawn, won 18 parliamentary seats in the June election with a campaign openly hostile to illegal immigrants - and there are now allegations that some Greek police are supporting the party.

Last week Golden Dawn MP Ilias Panagiotaros led a demonstration that closed down a performance of the Terence McNally play, Corpus Christi.

As police stood by, apparently oblivious, Mr Panagiotaros was filmed shouting racist and homophobic insults at the director of the play, and the actors cowering inside the Chyterio Theatre.
