The director of the Scottish National Gallery, Michael Clarke, is to retire from his post.

Mr Clarke, also deputy director of the National Galleries of Scotland (NGS), has been at the institution for more than 30 years.

He joined the Galleries in 1984, having previously worked at Manchester University and the British Museum.

He became Keeper in 1987 and then Director of the Scottish National Gallery in 2001.

Sir John Leighton, director-general of the NGS said: “Michael Clarke has had a hugely successful career at the galleries.

"With his depth of expertise, commitment to excellence and flair for accessible programming he has played a key role extending the national and international reach and reputation of NGS.

"His contribution will be greatly missed but we all wish him well in his retirement.”

From 1998-2004, Michael led the building of thePlayfair Project at NGS which linked the National Gallery with the neighbouring Royal Scottish Academy building.

The National Gallery complex now attracts 1.4 million visitors every year, making it the third most popular visitor attraction in Scotland.

He has also been closely involved in the development of the major project to transform the Scottish Galleries at the SNG, which is due to begin on site later this year and to be completed in 2018.

He has organised several exhibitions for the Scottish National Gallery, including Lighting up the Landscape: French Impressionism and its Origins (1986), Cézanne and Poussin (1991), Monet to Matisse (1994), Monet; the Seine and the Sea (2003), Impressionist Gardens (2010), The Art of Golf (2014) and Inspiring Impressionism (2016), as well as being a guest contributor to exhibitions organised abroad.

Mr Clarke's special interest lies in the French School, of which he has acquired many paintings and drawings for the Scottish National Gallery’s collection.

He was also instrumental in acquiring two Titian paintings, Diana and Actaeon and Diana and Callisto from the Bridgewater Collection, in partnership with the National Gallery in 2009 and 2012.

In 2004 he was made a Chevalier de l’Ordre des Arts et des Lettres by the French state, he was made a Fellow of the Royal Society of Edinburgh in 2008 and he was awarded a CBE by the Queen in 2009.
