The trial of a physics teacher accused of having drunken sex with a student in a plane toilet collapsed today.

The jury at Bristol Crown Court told the judge they could not decide if Eleanor Wilson, 29, was guilty or not.

She was accused of four charges of sexual activity with a child by a person in a position of trust.

The Crown Prosecution Service now has a week to decide if it will seek a retrial.

Wilson was accused of sleeping with the boy on their British Airways flight home from a school trip to Africa in 2015

The panel had been deliberating for ten and a half hours.

Wilson, 29, of Dursley, Gloucestershire, was accused of having drink-fuelled sexual intercourse with the teenager on a British Airways flight home from an overseas camping trip in August 2015.

She also allegedly kissed and cuddled the boy on three other occasions.

Wilson denied four charges of sexual activity with a child by a person in a position of trust.

Judge Peter Blair QC, the Recorder of Bristol, stopped the trial after the foreman informed him there was not a 'realistic prospect' of reaching majority verdicts on any of the four charges of sexual activity with a child by a person in a position of trust that Wilson faced should they be given more time.

Judge Blair told the panel: 'I am going to discharge you now from returning verdicts on this indictment but can I extend my grateful thanks to you on behalf of the court service for all the work you have been doing for the last three-and-a-half weeks.

'This happens from time to time. Every year I keep a spreadsheet of trials that I do and the outcomes that there are and each year there are quite a number of juries that have the same perfectly legitimate outcomes as this, what we call a hung jury.

'It is part of the system and you shouldn't in any way beat yourselves up about it.'

Virginia Cornwall, prosecuting, asked for seven days for the Crown Prosecution Service to consider whether it wished to seek a retrial.
