Yaxley-Lennon, who uses the pseudonym Tommy Robinson, was arrested and jailed last year for potentially prejudicing a trial after the Facebook broadcast outside a trial of men accused of sexually abusing teenage girls.

Yaxley-Lennon has built a large online following with links to international white nationalist and far-right movements.
Judge Victoria Sharp said Friday the court will consider what penalty to impose for the contempt at a later date
