London - Hollywood actress Meryl Streep dropped in on parliament on Wednesday to watch Britain's top politicians do battle, studying for a role as the only woman to become the country's prime minister: Margaret Thatcher.
The 61-year-old Oscar-winner will star in The Iron Lady
, a film that recalls the days leading up to the 1982 Falklands War - a conflict in which Britain repelled an Argentine invasion of the remote, disputed territory in the south Atlantic Ocean.
Success in the war helped improve Thatcher's popularity ratings after the early 1980s recession and contributed to her Conservative party's 1983 election victory.
Streep, who has won acclaim for her part in films such as The Deer Hunter
, Kramer Vs Kramer
and Out Of Africa
, witnessed Prime Minister's Questions - a showcase event in parliament where current PM David Cameron gets a weekly grilling.
