Some 18 activists wearing orange hi-vis vests burnt pages of injunctions that had been individually served on them, on the pavement outside the court building. It comes as a High Court hearing takes place over three injunctions granted to National Highways in late September and October, covering the M25, Port of Dover, and major A roads around London.

       Demonstrator Nick Onley, 59, from London, said: "It's a sign of our determination to carry on protesting, to carry on raising this issue until we see some action that we can believe in".

       Mr Onley, a food bank worker and community musician, added: "We're just making it clear that we intend to continue our protest until we have some clear, meaningful statement that we can trust from the Government that they are actually intending to go ahead with insulating and decarbonising the country".
