A misconduct hearing against a former Eton College deputy headmaster has been de-listed just two days after it was publicly announced.

Mohammed Tanweer left the prestigious independent school last year following an exam board investigation into allegations about exam questions being leaked.

On Monday, a professional conduct panel hearing involving Mr Tanweer was listed for 29 October to 1 November.

The Teaching Regulation Agency website did not give details of the allegations he was set to face.

However, an update posted today said the formal notice had been “removed”, and his case was removed from the listings.

A Department for Education spokesperson said that TRA processes “allow for a decision to be taken at any point up until the first day of a hearing whether a case should progress to a professional conduct panel”.

However, the DfE said it was unable to comment on the reasons why Mr Tanweer’s case had been de-listed because of the legal process.

Last August, the Guardian reported that Mr Tanweer left Eton following an investigation by the Cambridge International Examinations (CIE) about allegations of the sharing of questions with other teachers ahead of an upcoming A-level equivalent exam.

In a statement at the time, Eton College said: “Eton College can confirm that following an investigation by the Cambridge International Examinations Board into maladministration, the board concluded that there had been a breach of exam security by one of Eton’s teachers in relation to one of the Pre-U Economics papers.

“Eton took this matter extremely seriously and co-operated fully with CIE’s investigation throughout.

“The teacher concerned has left the school. Whilst pupils had done nothing wrong, they were inadvertent recipients of confidential information and so the board awarded them assessed marks for that paper according to its established method. Eton College deeply regrets that this incident occurred.”

CIE runs international education programmes and qualifications including the Cambridge Pre-U, which is used as an alternative to A levels.
