Model Daisy Lowe and Spice Girl Mel B have become the latest celebrities to back the activist group Extinction Rebellion who plan to disrupt London in a major protest over the next fortnight.

The 30-year-old Vogue cover girl, Daisy, posed with an 'XR' badge alongside her friend Mel B.

Daisy, who was born in Westminster, said she backed the plans to disrupt Parliament by thousands of protesters who plan to block all routes into the area surrounding the House of Commons.

Spice Girl Mel B, 44, added: 'I was born a fighter, I stood proud as a mixed race woman and championed girl power.

'I fight for victims of abuse and I'm giving all my support to these brave activists to make a better world for us all.'

'I am so grateful that Extinction Rebellion exists,' Daisy said.

'It's time for change. It's time for rebellion and I love being able to be part of it.'

She joins The Crown's Oscar-winning actor Olivia Colman, broadcaster, author Stephen Fry, and TV comic Alan Carr in backing the activists.

The actors donned 'X' badges at the Royal Albert Hall and were joined by comedian Asim Chaudry, and American actress Crystal Clarke.

Chaudry and Colman's support for the protesters may land them in opposition to British Airways, who have a fleet of aircraft operating from London City Airport which is to be targeted by XR.

They both appear on a BA in-flight safety films with other stars such as Michael Caine, Joanna Lumley and David Walliams.

It can also be revealed that animator Jamie Hewlett, who won a BAFTA in 2009 with pop star Damon Albarn, will project his artwork onto Parliament and Big Ben next week to promote XR's cause.

Hewlett, 51, co-creator of the comic book Tank Girl and the virtual band Gorillaz with Albarn, has created a special artwork promoting XR's slogan 'Tell the Truth' which is set to be emblazoned across the heart of Westminster.

Other large scale projections will take place across the country, the group have said, as they pressure the Government to 'act now' on climate change.

On Friday night, the 'projection rebellion' began with a display of the Extinction Rebellion logo on the Tate Modern on London's South Bank.

XR say that there will be a similar action at the Trellick Tower, west London, this weekend.

The protests are set to bring disruption to the centre of the capital as part of an 'international rebellion' around the world calling for urgent action on the climate and wildlife emergencies.

Extinction Rebellion spokesman Joel Scott-Halkes said: 'We are going to the Government and specifically what we're going to do is sit down peacefully in the roads'

A fortnight of further action is planned with activists saying they plan to shut the streets leading to Westminster, targeting sites including Lambeth and Westminster Bridges and Trafalgar Square, each held by people from different parts of the country.

Protests will also be held outside government departments, calling on them to outline what their plans are to tackle the climate emergency, with protests including a farming group with a pink tractor.

Other actions include processions, marches and a peaceful sit-in at City Airport where they will try to hold the space for three days.

The protesters say they have not yet decided if they will hold a silent vigil to mark a lack of action in the Queen's Speech on October 14 or to try to shut it down.

Extinction Rebellion spokesman Joel Scott-Halkes said: 'We are going to the Government and specifically what we're going to do is sit down peacefully in the roads.

'We're going to blockade and shut down every single road going into the central area of Westminster around the UK Government.

'We are going to very loudly, very clearly, very respectfully say that if a government is taking its people towards extinction, it is not a government anymore that we respect.'

Another spokesman Robin Boardman, 21, said it could be five times bigger than the protests which brought major disruption to London in April and saw more than 1,100 arrests,

As many as 20,000 to 30,000 people could be involved this time, he said.

While Met Assistant Commissioner Nick Ephgrave has warned of the strain policing protests will put on the force, Mr Boardman said the protests were not about the police, 'it's about putting pressure on the Government'.

Major events are also planned around the world in Australia, in Europe – in Berlin, Madrid, Amsterdam – and in the US in New York and Washington DC.

Extinction Rebellion is calling on the Government declare a climate and ecological emergency, act immediately to halt wildlife loss and reduce greenhouse gas emissions to net zero by 2025.

They want to see the Government create and be led by the decisions of a Citizens' Assembly on climate and ecological justice.

Earlier in the year, Parliament declared a climate and environment emergency and the Government has passed a law to cut emissions to net zero by 2050, far later than the activists are demanding.

Mr Boardman said: 'Right now we're looking at a disastrous situation which demands so much radical action. It doesn't demand the piecemeal action we're currently seeing across the world.

'It needs radical change to our system because currently what we're looking at is accelerating destruction, ecosystems across the world being wiped out at rates that are rapidly increasing.

'It highlights we are in a system that is criminally failing us, a system, economically, that cannot handle what is happening, it needs change in a dramatic way.'

British police arrested ten Extinction Rebellion activists in London ahead of the planned new round of protests on Monday, the force revealed.

A spokeswoman for London's Metropolitan Police said seven women and three men had been arrested on suspicion of conspiracy to cause public nuisance.

Extinction Rebellion said the arrests represented an 'escalation of pre-emptive tactics by the government and police' and was a sign that it was considered a 'significant movement' by the authorities.

'We ask that the government focus their attention and resources on responding to the climate and ecological emergency which threatens us all,' it said in a statement, calling for donations of kitchen and sound equipment, food and tents and other items to replace material seized on Saturday.

The group staged 11 days of protests in London in April that disrupted public transport and roads.

On Thursday, Extinction Rebellion activists used a fire engine to hose red liquid at the British finance ministry's headquarters in London to draw attention to what they said was the government's failure to avert climate disaster.
