The co-founder of a pro-Palestinian campaign group sought on Monday to challenge the British government's decision to ban the group under anti-terrorism laws, a move her lawyers said had "the hallmarks of an authoritarian and blatant abuse of power".

More than 100 people protesting the decision to proscribe Palestine Action as a terror group have been arrested across the UK. Demonstrations in support of the pro-Palestine activist group took place in London, Edinburgh, Manchester, Bristol and Truro on Saturday.

More than 100 people have been arrested across the UK during protests in support of Palestine Action. The group was banned as a terrorist organisation in June. In Liverpool city centre, four people were arrested on suspicion of terrorism offences on Sunday afternoon, Merseyside Police said.
