A former British spy who handed over data on western intelligence operations to the Soviet Union is celebrating his 90th birthday.

George Blake was eventually jailed for 42 years for his betrayal before he fled to Moscow in 1966 where he has remained ever since.

Russian president Vladimir Putin has said his work deserves the highest praise and respect.
