Sir Alan Davies' bonus payments were revealed at a conference
Teachers at a north London secondary school have declared a vote of no confidence in a head teacher awarded £80,000 in bonuses last year.
Unions members at Copland Community School in Wembley also voted to ballot for strike action, claiming some staff were suspended for leaking the details.
Sir Alan Davies' bonus payments were revealed during a national teachers conference earlier this month.
The head teacher has previously said he believed he deserved to get the bonus.
The Audit Commission confirmed it was looking into the bonus scheme and had raised the issue with Brent Council.
In a series of motions, the National Union of Teachers (NUT), the Association of Lecturers and Teachers (ALT) and the NASUWT unions, called for a full investigation by the Audit Commission into the "bonus culture" at the school.
Hank Roberts, the school's NUT representative, said: "We call on our teachers and governors to request that the whole governing body be given full details of all bonuses given to staff over the last seven years."
Another motion called on the school's chairman of governors Dr Indravadan Patel to stand aside.
The motions will be presented to school governors at an emergency governors meeting next week.
The school has so far not commented on the no confidence vote.
