Negotiators continue to urge the man, who is several metres above the Big Ben clock tower, to leave as night falls.
The man, who climbed the tower around 7:20 a.m. Saturday and was holding a Palestinian flag on a ledge, spoke several times with emergency services and negotiators, but as of 6:45 p.m. he had still not agreed to come down.
In a video posted on Instagram, he tells negotiators that he will come down “on his own terms.”
Footage shows negotiators on the ladder appearing to express concern about his leg injury, saying there was “quite a lot of blood” and that his clothes were not warm enough as temperatures dropped after sunset.
However, the man insists he is safe and states, “I will go down on my terms, I said that. But right now I say I am safe.
“If you come near me, you will put me in danger and I will rise higher.”
A video posted on social media earlier on Saturday showed a man climbing over a fence surrounding the parliament building, with security taking no action.
Conservative MP Ben Obese-Jektey told X that it was necessary to find out how the man managed to get into parliament.
He said: “Every day in Parliament I see dozens of armed police officers patrolling Portcullis House and the parliamentary estate. Where were they today?
“MPs and parliamentary staff must be given a full explanation on Monday as to how this protester managed to get past security so easily.”
A parliamentary spokesman said: “We are aware of an incident that took place in the Houses of Parliament this morning, which is being dealt with by the Metropolitan Police, supported by the London Fire Brigade and the London Ambulance Service.
“Parliament takes security issues very seriously, but we will not comment on the details of our security measures or their easing.
“As a result of this incident, tours of the parliamentary estate have unfortunately been cancelled.”
Westminster Bridge and Bridge Street remain closed, but the crowds that previously lined the edges of the cordons have thinned.
London bus routes 3, 11, 148, C10 and 159 continue to change.
