The Tate has announced the line-up for its 2015 programme of exhibitions, including shows from some of the art world's biggest names.
At the top of the list is a major retrospective of Barbara Hepworth (1903-1975) in the summer, the first to be held in the UK since the 1960s.
The event is particularly timely as Hepworth is experiencing renewed interest among collectors - with a new artist record set in June.
Alexander Calder (1898-1976) is also the subject of a retrospective, the first to be held in the UK, which is due to take place in the autumn.
