Climate activist group, Extinction Rebellion, have have superglued themselves around the Speaker's chair in the House of Commons chamber.
Superglueing themselves around the Speaker's chair in the House of Commons chamber is just one of the various ways that Extinction Rebellion have attempted to gather parliament's attention today.
50 members have been protesting in and around the building, with some padlocking themselves to the gates.
Another activist scaled the scaffolding surrounding Big Ben and held a giant banner that read: "Let the people decide: citizens assemblies now"
The group have said that the demonstration is in support of a "citizens' assembly" to help deliver action on the climate crisis.
The campaign group tweeted a photo showing three women standing hand-in-hand in front of the green leather chair where the Speaker sits when parliament is in session.
Two men stood either side holding banners. One read "Let the people decide" and the other said "Citizens' assembly now".
The protesters managed to enter the building with the banners as they were hidden in a "bag within a bag".
The group wrote on Twitter: "Extinction Rebellion supporters have superglued around the Speaker's chair inside the Commons chamber."
"Right now inside parliament a speech is being read out demanding a citizens' assembly now: "We are in crisis. We cannot afford to carry on like this".
"It is possible to act on climate and costs in a way that is fair and supports everyone. But our political system is too out of date and out of touch to see beyond the next election cycle and do what needs to be done. We need a new way of making decisions, where more voices are heard, not just those at the top. We need the true diversity of the country to be represented
"We need a citizens" assembly, now. Citizens' assemblies empower ordinary people to make decisions that benefit everyone. Decisions that can get us out of this mess and make life better, safer, fairer for all of us."
A Commons spokesperson said: "We are aware of an incident on the parliamentary estate and are currently dealing with the situation as a matter of urgency."
The Metropolitan police tweeted: "The Met is aware of a demonstration by a number protesters at the Palace of Westminster. Met police and parliamentary staff are responding."
In a statement, Extinction Rebellion described the actions as the "opening act" for further protests it has planned this month, including a three-day occupation of Hyde Park, "which itself will act as a launch event for a five-phase plan to bring 100,000 people on to the streets in civil resistance next spring".
A citizens' assembly on solutions to the climate crisis has been one of the group's key demands since 2018.
Alanna Byrne, a spokesperson for XR said: "Independent citizens' assemblies can show that those blocking progress in Westminster have no democratic mandate to continue destroying the environment and give power back to people."
The Commons and Lords are in recess until Monday.
