Staff at Royal Bank of Scotland’s Bishopsgate offices, where climate change campaigners this morning held a four-hour demonstration on the bank’s trading floor, have been told they can leave the building but must remain “vigilant” while the protest group decides if, and how, it will stage further demos.

At 8:30 BST this morning, seven Climate Camp protesters made their way onto the trading floor of RBS, where they glued their hands together, according to a spokesman for the Metropolitan Police. They were joined by 20 protestors, who congregated outside RBS' offices on Bishopsgate, rallying against the bank's investment in fossil fuel projects.
