Palestine Action has been banned from protesting outside Parliament just hours ahead of Government plans to proscribe the group as a terror organisation.

Met Police have imposed an exclusion zone around Parliament and told protesters they face arrest if they enter the area.

In a statement on X, the force wrote: "Public Order Act conditions have been imposed on the protest in support of Palestine Action due to take place tomorrow.

"The protest must not begin before midday and must end by 3pm."

Met Police also included a map of the exclusion zone and warned that the protest cannot take place within the area.

The protest has been moved to Trafalgar Square, where dozens of people have gathered.

The Metropolitan Police Commissioner, Sir Mark Rowley, said he was "shocked and frustrated" at the group's plans to protest ahead of the ruling.

The protest has begun just shortly before Home Secretary Yvette Cooper will proscribe Palestine Action as a terrorist organisation after two of the group's activists infiltrated RAF Brize Norton and damaged two Voyager aircraft.

The banning of Palestine Action will put the organisation on par with Hamas, al-Qaeda and Isis.

Rowley wrote on X: "I'm sure many people will be as shocked and frustrated as I am to see a protest taking place tomorrow in support of Palestine Action.

"This is an organised extremist criminal group, whose proscription as terrorists is being actively considered.

"Members are alleged to have caused millions of pounds of criminal damage, assaulted a police officer with a sledgehammer, and last week claimed responsibility for breaking into an airbase and damaging aircraft."
