Dame Helen Mirren could be invited to tea at Buckingham Palace after she was crowned as best actress at the Oscars for her stoic portrayal of Queen Elizabeth II. A meeting with Her Majesty would follow a glittering clean sweep for the British actress this awards season, after the role garnered her a Screen Actors Guild Award, a Golden Globe and a BAFTA Award from the British Academy of Film and Television Arts. At the Oscars, the film's director Stephen Frears suggested that he, Mirren and screenwriter Peter Morgan would visit the real Queen at Buckingham Palace in March. Robin Millard reports.
