Oxford Climate Choir has taken part in a 200 singer-strong flash mob to protest against oil giant BP.

On Saturday, November 30, visitors at the British Museum's Great Court were taken by surprise when members of the Climate Choir Movement began a harmonious protest.

The group sang a three-part harmony with lyrics urging the museum to "drop BP" and "not take their dirty money".

The choir's performance follows the museum's decision last year not to renew BP's five-year sponsorship of its exhibitions, although the oil giant has since pledged £50 million towards the museum's 10-year redevelopment plan.

Critics have raised concerns about potential conflicts of interest, given the museum's chair, George Osborne, has links with BP.

"BP is not giving money to the British Museum out of the goodness of its heart.

"This is a strategic decision to look like a responsible company, to gain social consent for continued oil and gas exploration."
