David Cannadine points out that the price of Leonardo’s Salvator Mundi, which sold for £333m last November, represents over half of central government’s total funding for museums last year. Of 266 museums he surveyed, only half had a dedicated acquisitions budget and in most cases it was less than 1% of their expenditure. The Art Fund report, entitled Why Collect?, calls for a national debate on the challenges over museum acquisitions.
