London Metropolitan policewoman faces being fired after 'having sex while taking part on Nigerian Big Brother without permission'

A British policewoman faces the sack for defying her bosses to appear a reality television programme - before appearing to sleep with a man on the show.

PC Khafi Kareem, 29, from the Metropolitan Police, was warned not to take part in Nigerian Big Brother this year.

But she was granted unpaid leave and entered the show, in which she has formed a relationship with fellow contestant Ekpata Gedoni, 31, the Sun reported.

Audiences in Nigeria have been caught up in their liaisons, of which there has been three, but she will now be the subject of an investigation by the Met's Directorate of Professional Standards.

And her colleagues have expressed their dismay at her 'tarnishing' the force's reputation with her antics. 

The officer was used as a 'poster girl' for the Met, posing alongside Met Commissioner Cressida Dick to encourage black and female recruitment and celebrate 100 years of women in the force.
