The entrance to the Canadian High Commission in Trafalgar Square has been blocked by climate campaigners who’ve built a huge oil pipeline around the building. The protest comes as Canadian PM Justin Trudeau touches down in London for the Commonwealth Heads of Government meeting.

The pipeline is branded ‘Crudeau Oil’. Climbers have also scaled two entrance pillars to drop banners rebranding the building ‘Crudeau Oil HQ’.

The blockade is a protest against the Trudeau government’s plans to build a huge oil pipeline from the Alberta tar sands across indigenous lands to ports in British Columbia. The massive protest pipeline was installed at 6.30am this morning by 30 Greenpeace volunteers and runs from the main entrance of Canada House to the consular entrance on Cockspur Street.
