French prosecutors have said British teachers who were responsible for looking after a 12-year-old girl who drowned on a school trip should be jailed for three years.
Steven Layne, Chantelle Lewis and Daisy Stathers, from Wolfreton School in Willerby, near Hull, are accused of the French equivalent of manslaughter by gross negligence following the death of Jessica Lawson in July 2015.
The schoolgirl, who was the youngest child on the trip, became trapped after a pontoon capsized in a lake near the city of Limoges.
A trial at the Palais de Justice in the French town of Tulle heard how Ms Lewis and Ms Stathers began to "panic" after noticing Jessica was missing, with both becoming emotional on the witness stand during Tuesday's proceedings.
Mr Layne said he thought the pontoon was a safety feature and saw no signs of distress when he looked at the lifeguard after it capsized.
The youngster's mother, Brenda Lawson, told the court she expected the teachers to have "respect and integrity" during the trial.
During her closing speech, prosecutor Myriam Soria told the head of jurisdiction in Tulle, Marie-Sophie Waguette, she recommends three years' jail time for the three teachers, as well as for the lifeguard Leo Lemaire.
Ms Soria also advised Ms Waguette that the local authority in the town of Liginiac should be fined €45,000 (£39,230) for its alleged part in Jessica's death.
In her speech, the prosecutor said: "Jessica Lawson was a good swimmer. She was a little girl.
"Her swimming should have been monitored with vigilance."
Ms Soria said none of the teachers could see where Jessica was during the swim due to a lack of surveillance.
Addressing the pontoon itself, the prosecutor said the local authority "knew about instability and knew about its age."
Jessica's parents, who have followed proceedings through an interpreter, will find out whether the teachers are guilty on Wednesday.
