The adopted son of Pink Floyd guitarist David Gilmour could face jail today when he is sentenced for going on the rampage at a student fees protest.

A court heard yesterday that Charlie Gilmour shouted "We're going to break all the laws" during a day of riots late last year.

The 21-year-old, from Billingshurst pleaded guilty to violent disorder in May after joining thousands demonstrating in London's Trafalgar Square and Parliament Square.
