Lots of people being arrested, either walked out or carried out.

And each time people are shouting... The British government...

have betrayed the British people.

Palestine action is back.

That last clip you heard was from earlier today as Palestine action supporters celebrated outside court in central London.

It's been ruled the decision to ban them was in fact illegal.

Our reporter Nick Johnson told me more.

Judges said that Palestine Action, they did acknowledge Palestine Action, the group, uses criminality to promote its aims.

But they said those activities had not crossed the very high bar needed to designate it as a terrorist organisation.

So effectively, they said the government's decision to ban it as a terrorist group was disproportionate.

Because at the time when it was banned, the supporters of the group said it was laughable that it was on the same list as Islamic State and Al-Qaeda.

Yeah, that's right.

I mean, the prescription laws here in the UK, the government can prescribe an organisation if it commits, prepares.

promotes encourages or is otherwise concerned with terrorism there are a lot of groups who are prescribed here in the UK and you've named some of them ISIS for one of the national action the far-right group another one and a lot of the supporters yes were saying it's laughable that we're on the same sort of page as those groups particularly they say is the the protests that they were taking part in they said were a lot with direct action they some they were saying this is something that protest groups up and down the country have been used to to using for years and

How embarrassing is this for the government and some key figures within the government?

Very embarrassing, I think, is the long and short of it.

I think it was also a surprise that the decision went the way it did today.

I think the government thought that it was nailed on, that this would go their way.

The Home Secretary at the time, Yvette Cooper, was the one who was leading the Home Office here in the UK and the one responsible for the ban.

But it's Shabana Mahmood.
