They’re doing fantastic deals on five-star hotels in St Petersburg the weekend the Francis Bacon exhibition opens at the Hermitage. With tensions between Russia and the west at their highest since the Cold War, ‘no one’, I’m told, wants to come here. No one, that is, except large numbers of elderly but well-heeled people from the Norwich area, many of them trustees and friends of the University of East Anglia’s Sainsbury Centre for Visual Arts — co-organisers of the exhibition — who have flown out here for the gala opening.
