London modern and contemporary art dealer Anthony d'Offay has granted a donation that is making history: his giant collection of 725 works of art have just been given jointly to the Tate Gallery (London) and to the National Gallery of Scotland (Edinburg) and is conservatively valued at a total of £125m.

Valérie Fougeirol, director of Paris Photo and its London edition, has left the company "by mutual consent", forcing the cancellation of Photo London, scheduled for this May.

Until 30 June the Galeries nationales du Grand Palais in Paris hosts the major exhibition about Marie-Antoinette, who was undoubtedly France's most notorious queen. She was adulated on her arrival in Versailles, where her beauty, vivacity and intelligence were widely admired. Worried by her popularity, courtiers at Versailles attempted to limit her political influence. But the young queen was destined to make an impact. Marie-Antoinette soon became known as a patron of the arts. She brought about changes at Versailles in the realms of decorative arts, music and fashion. However, her extravagance came in for sharp criticism. The young queen was dismissed as "the Austrian" and considered a spendthrift, a schemer and a counter-revolutionary. The Grand Palais provides a fascinating insight into Marie Antoinette's strong and complex personality through this exhibition of nearly 300 works from all over Europe: a rare opportunity, considering that the last tribute of this scale paid to this famous historical figure dates back to 1955
