Two environmental campaign groups will be allowed to help appeal against the sentences given to five climate protestors who took part in demonstrations that blocked the M25.
Just Stop Oil (JSO) founder Roger Hallam was jailed for five years and activists Daniel Shaw, Louise Lancaster, Lucia Whittaker De Abreu and Cressida Gethin were jailed for four in July for their roles in disrupting traffic on the motorway in November 2022.
Friends of the Earth (FoE) said it and Greenpeace UK have been allowed to intervene in support of the five when they challenge their jail terms in court next month.
FoE said it would argue the sentences breach human rights legislation.
