WHY Collect?, a report on museum collecting by historian Sir David Cannadine, commissioned by Art Fund and the Wolfson Foundation, calls for increased investment in museums and their collections.

The report "highlights the ever-widening gap between the spiralling prices of works on the international art market and the limited acquisition funds available to museums and galleries in the UK."

Cannadine’s analysis of museum and gallery collecting traces its history from the 1830s to the present day, and is accompanied by 11 case studies which explore various facets of the social and cultural impact of collecting.

Cannadine cites the £333m recently paid for Leonardo da Vinci’s Salvator Mundi.

It says the museums of the UK have experienced a decade of diminished funding as an example of the cost of art.

The morale, confidence and the numbers of curatorial staff, it says "have been in serious decline for some time".
