Two Greenpeace activists have scaled a crane at the back of Parliament to protest US Secretary of State Rex Tillerson's visit.
They have been up there in heavy rain for about an hour.
It is believed they are working to unfurl a banner urging action on climate change.
There is a low security presence, although many construction workers have put down their tools to watch the protesters in action.
