A TEACHER from Dursley appeared in court today (Monday) accused of sexual activity with a 16-year-old pupil.

Ellie Wilson, 29, of The Rope Walk, Dursley, is alleged to have had sexual activity with the teen on August 2, 2015.

Wilson, who taught science, had sex with a 16-year-old pupil in an aeroplane toilet and later told him she was pregnant and would have an abortion, Bristol Crown Court heard.

The pair then went on dates to Nando's and a country park and he bought her chocolates and flowers in the belief they were in a proper relationship.

But the sordid fling was exposed when a jealous friend of the victim tried to blackmail her into having sex with him.

She refused to comply and confessed to her superiors at a Bristol secondary school, which cannot be named for legal reasons.

She no longer works at the school and has been struck off on recommendation from the National College for Teaching and Leadership (NCTL).

Wilson, of Dursley, denies four charges of sexual activity with a child by a person in a position of trust in August and September 2015.

The opening of the trial heard the boy describe in sordid detail how the sexual encounter unfolded on a flight back from a school trip to Africa.

Prosecutor Virginia Cornwall told the court how the pair became close during an outdoor camping holiday in Africa.

They would 'pair up' for activities and stay up late talking after other teachers and pupils had gone to bed, which led to an “erosion of boundaries”.

She held his hand on the coach back to the airport, where the group caught an Airbus flight back to the UK.

All the teachers and pupils were drinking on the flight, and the victim described himself as “fairly intoxicated” when the sexual encounter took place.

Wilson confided in the boy that she was pregnant at school a month later, the court heard.

The 16-year-old said he struggled to cope after she allegedly told him about the pregnancy.

He said in the recorded police interview: “I’m looking at this teacher and everyone is calling her ‘Miss’ but I know she's got my baby inside of her.”

Ms Cornwall described Wilson, who was a science teacher and head of Key Stage Four at the school - as a 'risk taker'.

She said: “This defendant was in 2015 considered a bright and capable teacher.

“These are offences alleging a breach of a position of trust. We assume, expect and want our teachers, our social workers and those that look after children and educate them to behave in a way that is not predatory that is not sexual.

“It was the circumstances in which the two interacted on the school trip that led to an erosion of boundaries and it was her responsibility as the adult to ensure there was no erosion of boundaries."

The trial continues.
