A murderer who strangled his girlfriend with a cord from his games console just after having sex with her has been jailed for life.

Jermaine Flavius, 23, of Islington, wrapped the body of Kelly Sinnot, of Bethnal Green, in his lounge rug and dumped her in a Buckinghamshire field.

He pleaded guilty at the start of his trial at the Old Bailey on Friday.

Flavius had affairs with several other women and treated Miss Sinnot as a sex object and a punch bag, the court heard.

She had a tattoo on her back which read "Property of Flavius".

To hide her identity, Flavius smashed her facial bones with a broom handle and a wooden tool.

He killed her after they had sex at his house in Goswell Road, east London, on 2 October last year.

Three days later a passer-by found her body at the entrance to a field in Galley Lane, Great Brickhill, near Milton Keynes.

Today Flavius was ordered to serve a minimum of 15 years in prison.

"Kelly Sinnott was a young woman who formed a relationship and became besotted with Jermaine Flavius," said Detective Chief Inspector Terry Geraghty.

"Tragically, this infatuation resulted in her violent death."
