Valerie Singleton's wedding proposal to Eddie

The former Blue Peter and PM presenter Valerie Singleton has proposed live on air to Eddie Mair.

"I've lived for an awful lot of leap years and I've never actually asked anyone to marry me," she said. "I can die happy now."

Ms Singleton returned to co-present a special edition of PM to mark 'leap day', the extra day which happens every leap year on the 29th February.

She used the occasion to seize on the tradition that a woman can be the one to pop the question in a leap year.
