Police have been called to the Palace of Westminster after a man was seen climbing up the tower which houses Big Ben.
Video on social media shows a barefoot man stood on a ledge several metres up the Elizabeth Tower holding a Palestinian flag.
Police said they were called to the scene at 7:24am this morning.
A fire engine has now raised a cherry picker to the same height as the man’s position on the tower.
Three people standing on the crane are talking with the man, who is several feet away.

‘When we saw the man we thought this is for real,’ says one onlooker.
The protester has been sharing videos on Instagram from his viewpoint on the tower as a woman in plain clothes speaks to him from the cherry picker.
The woman says: “At some point you have to come down. How long do you think you are going to be there? How long do you think you are able to be there?”
Her voice is then barely audible as she appears to say “your message was to say ‘Free Palestine'” before she encourages him to come down.
Photographs have shown the man sat on a ledge with the flag and a keffiyeh, a headdress worn by men in the Middle East, wrapped around the decorative stonework on the tower.
A large red stain which appears to be blood can be seen on the side of the tower around the protester’s feet.
Meanwhile, the whole of Westminster Bridge was closed for part of this morning as emergency services responded to the incident.

A spokesman for London Fire Brigade (LFB) said crews from Lambeth, Chelsea, Soho and Islington fire stations have been deployed.
At least nine emergency service vehicles have lined the street in central London as crowds look on from beyond a police cordon.
A parliamentary spokesperson said: “We are aware of an incident on the Parliamentary Estate this morning, which is being handled by the Metropolitan Police, assisted by the London Fire Brigade and the London Ambulance Service.
“Parliament takes security extremely seriously, however we do not comment on the specifics of our security measures or mitigations. As a result of this incident, tours of the Parliamentary Estate today have unfortunately had to be cancelled.”
It comes as around 100 people have started to gather for a pro-Palestine protest in central London.
The crowd has gathered on the corner of Parliament Square and appear to be showing support for the man who climbed up Big Ben.
They are holding up a sign that reads: “Labour Tories BBC you show Russia’s crimes but hide Israel’s … why?”

‘Gaza not for sale’ on Trump golf course
The protest in Westminster comes as the Palestine Action group said it had sprayed “Gaza is not for sale” on Donald Trump’s Turnberry golf course in Scotland.
Sharing an image of the vandalism on Saturday morning, the group wrote on X: “Whilst Trump attempts to treat Gaza as his own property, he should know his own property is within reach.”
The Turnberry protest comes after the American president claimed the US will “take over the Gaza Strip and we will do a job with it too”.
