Comedian Sacha Baron Cohen and his wife actress Isla Fisher have donated more than £670,000 to charity, it has been reported.

The generous couple have given $500,000 (£336,000) to The Sunday Times Christmas appeal to help protect 250,000 children against a threatened measles outbreak in Syria, the newspaper said.

Sacha, 44, and Isla, 39 are also giving a separate sum of $500,000 to the New York-based International Rescue Committee which is run by former foreign secretary David Miliband.
