ENGLISH Defence League founder Tommy Robinson has been caged for 13 months for contempt of court.

The 35-year-old right wing activist was arrested last week after streaming an hour-long rant outside Leeds Crown Court.

Robinson, whose real name Stephen Yaxley-Lennon was listed on court documents, admitted committing contempt of court by publishing information that could prejudice an ongoing trial.

He was already on a suspended sentence for a previous contempt offence in Canterbury last year.

The right-wing activist was arrested during a protest on Friday outside the court with footage showing him being led towards the back of a police van and searched.

His arrest sparked a mass protest outside Downing Street as supporters called for his release.

Demonstrators held up #FreeTommy placards and police were scrambled to keep crowds under control.

Robinson founded the English Defence League in his hometown of Luton in 2009 and resigned from the group four years later.

The organisation clashed with police during a number of violent marches on Britain's streets.

The controversial political activist told his Facebook followers he was heading to Airdrie over the “joke” because it was a “free speech issue”.
