A physics teacher who had sex with a pupil in the lavatory of a plane was caught after a second pupil tried to blackmail her, a tribunal heard.

Eleanor Wilson, 28, was described as intoxicated when she flew back from Geneva and starting flirting with the boy at the back of the plane while caring for another poorly pupil, a panel heard.

The boy - who had drunk five mini bottles of wine - joined her in the lavatory for sex and oral intercourse without protection, it was heard.

The academy teacher, from South Gloucestershire, continued their relationship, texting and meeting up for drinks, despite rumours circulating at school.

But the relationship came to light seven months later when another pupil emailed Wilson saying he would reveal the tryst unless she had sex with him, it was said.
