Sky News has filmed UKIP's current leader Gerard Batten taking part in an anti-Muslim rally last weekend which descended into clashes between protesters and police.
He was marching alongside members of a controversial group set up by a former football hooligan to unite supporters from different clubs against Islam.
UKIP's former leader Nigel Farage has warned Mr Batten to 'be careful what company he keeps'.
Sky's Home Editor Jason Farrell reports from Sunderland.
