Trailer released for new Princess Diana film

A trailer for a new film dramatising the final years of the life of Princess Diana has been released today.

The new film, which is released next month, delves into her relationship with the surgeon Hasnat Khan as well as her humanitarian campaigning.

Oscar-nominated actress Naomi Watts is set to play the leading role.

However, critics believe the film has been released too soon after Princess Diana's death.
