Thatcher family refuse Iron Lady screening

Meryl Streep's performance in The Iron Lady has divided opinion even before the film has gone on general release.

While some critics have praised it as a film, others - including Lady Thatcher's family - object to the portrayal of the former prime minister as a frail victim of dementia and have refused invitations to a private screening.

The film's director Phyllida Lloyd told BBC Radio Four's World At One much of the film was "pure imagination".
