Since 2010 there have been 14 protest art performances by the art collective "Liberate Tate" demanding the Tate to "disengage from BP as a sponsor, and stop allowing Tate to be used to deflect attention away from the devastating impacts that BP has around the world." BP is criticised for operations in relation with Petroleum exploration in the Arctic, the Deepwater Horizon oil spill, Oil sands and climate change. The artists involved in the protests are referring to a deal between BP and the Tate: BP pays £224,000 a year to the Tate. The Tate presents the brand BP in return. In June 2015 a group of artists occupied Tate Modern for 25 hours.
