A former Shrewsbury School teacher who filmed a pupil having sex in his room has been banned from teaching.
Michael Clarkson admitted to the General Teaching Council (GTC) hearing that he allowed "pupil A" to have sex in his room on a trip to Portugal.
He also told the hearing he had set up a hidden camera, but did not try to capture "any meaningful image".
The GTC called it a "very serious abuse" of trust. He can re-apply to the teaching register after four years.
The GTC Professional Conduct Committee also found that Mr Clarkson had failed to apply or enforce a reasonable curfew on the school tennis training camp "despite parents having been told that it would".
The committee also noted that during the Easter trip in 2006 students had been allowed to consume excessive amounts of alcohol.
Mr Clarkson was dismissed from Shrewsbury School over his conduct on the trip which took place between 6 and 13 April.
The GTC said: "Parents are entitled to expect teachers to observe the essential boundaries which are needed between teacher and pupil.
"Mr Clarkson's behaviour crossed those boundaries in an unacceptable manner and left his pupils feeling vulnerable, confused and frightened."
The committee said it was a "single episode during a 12-year career at Shrewsbury".
It also noted positive references from former colleagues and his recent employer.
Mr Clarkson is entitled to apply to the teaching register after four years.
He also has a right of appeal against the GTC decision.
