Oil companies such as BP and Shell are important sponsors of the arts in London, including theatre, opera and the visual arts. There was a lively debate on BBC Radio 4's Today Programme this morning about whether oil companies were cynically using the arts to give themselves social legitimacy.
Tate Britain will be celebrating 20 years sponsorship from BP today, and protests are planned outside the event due to BP's environmental record.
Greenpeace's Charlie Kronik and Sir Christopher Frayling debated the issue on the Today Programme at some length.
