A former Met Police sergeant’s ten year affair ended after he called his mistress by his wife’s names when they were in bed together, a court heard.
The relationship ended soon after and Ms Murphy then cut all contact with the former officer.
But Mr Birmingham sent her 36 emails to try and win her back while he was on holiday with his wife.

Ms Murphy reported him to police and he appeared in court charged with harassment.
He made the bedroom-based mistake just before they were about to have sex, the court heard.
Ms Murphy said: ‘That was that. All I could see was him on top of me naked, calling me ‘Karen’.’
Mr Birmingham, of Hailsham, East Sussex was cleared by JPs who said it was just part of the ‘cycle of emotions’ between the duo.
Dismissing the charge, JP Keith Sillitoe said: ‘There has been a long and fractious cycle of emotions between you for nearly ten years.’

The former lovers met during a crack house bust in South London in 2009.
Mr Birmingham is a highly decorated former Met Police Sergeant who worked as an officer for 30 years.
He started at Tooting in south-west London as part of the local crime squad and then later became a Detective Constable.
