Gary Oldman and Meryl Streep have been given Oscars boosts after walking away with the top acting trophies at the annual Richard Attenborough Regional Film Awards (RAFAs).

The public voted Oldman the Best British Film Star for his Academy Award-nominated role as George Smiley in Tinker Tailor Soldier Spy.

The thrilled star said, "This is the first prize for acting in a specific performance that I've received in over 20 years and that makes it all the more special."

Tinker Tailor Soldier Spy was also named British Film of the Year and Best Screenplay at the awards. The latter prize was accepted by Peter Straughan, who created the script with his late wife and writing partner Bridget O'Connor.

Oldman's fellow Oscar nominee Streep was also a big winner, claiming the critics' Best Actress honour for her portrayal of former British Prime Minister Margaret Thatcher in The Iron Lady.
