A miniature C16th painting of Elizabeth I that turned up in a house clearance sale is to go on show at the National Portrait Gallery.

The postcard-sized picture will be part of a major new autumn exhibition, Elizabeth I and Her People.

The BBC's Rebecca Jones spoke to the National Portrait Gallery's chief curator, Dr Tarnya Cooper, about the work.
