The number of arrests at Saturday's demonstration in London in support of banned group Palestine Action has risen to 532. The Metropolitan Police said the majority of arrests - 521 - were for displaying placards in support of Palestine Action at Westminster's Parliament Square, and one at a Palestine Coalition march.

A justice minister has vowed that supporters of a banned terrorist organisation "will feel the full force of the law" following arrests at a mass protest. The Met Police confirmed on Sunday that 522 people were held for displaying an item in support for Palestine Action, out of the total 532 arrests made during the policing operation.
