A female teacher who took part in an orgy with a sixth form girl during a two year affair has been banned from the classroom for life.

Francoise Jenkins, 45, a mother who was in a heterosexual relationship with one of the men who took part in the sex sessions, later paid him £13,000 "silence money" after they split up.

She had befriended the "vulnerable pupil" at Danum Academy, Doncaster, where she was a supply teacher, seducing her after obtaining her mobile phone number from the school's database.

Text messages included personal information about the "problems she was having with Individual C", the man she was living with.

They first had three in a bed sex on the night of the school prom. Ms Jenkins met the girl, Pupil A, for a drink after the school disco and took her home where she admitted having sex both with her and Individual C.

Pupil A later told the school she engaged in sexual activity with both Ms Jenkins and Individual C.

She said in a statement that as it progressed Individual C became more involved but they did not have full sex as she was "worried about becoming pregnant".

Another time Pupil A was invited to the house with a male friend, Individual A, and all four of them, including Ms Jenkins and Individual C, had sex.
