Free Tommy Robinson, far-right protesters demand

Hundreds of demonstrators gathered outside British Prime Minister's Downing Street office in London on Saturday calling for the release of far-right leader Tommy Robinson.

The protesters carried banners reading "Free Tommy Robinson" and waved British and English flags.

A number of protesters were seen trying to to breach security fences outside Downing Street.

Dutch anti-Islam lawmaker Geert Wilders travelled from the Netherlands to address demonstrators.

Robinson has been jailed for 13 months after live-streaming outside a criminal trial in violation of reporting restrictions.

The anti-Islamist founded the English Defence League, but left in 2013 concerned by its violent tactics.

"I acknowledge the dangers of far-right extremism and the ongoing need to counter Islamist ideology not with violence but with better, democratic ideas," he said at the time.
