Mike Tomlinson is among eight new members being appointed to the board of the Qualifications and Curriculum Agency, it was announced on Tuesday.

The secondary schools specialist is best known for his inquiry into the controversy surrounding last year's A Level exam results.

His report led to 1200 grades being changed and contributed to the resignation of then-education secretary Estelle Morris.

Tomlinson's appointment has been welcomed by the Liberal Democrats.

"We welcome the appointment of Mike Tomlinson, as it recognises the need for the QCA and the Tomlinson Inquiry into reforming education for 14-19 year olds to work together," said the party's education spokesman Phil Willis.

"The QCA and the Department for Education and Skills should make a further announcement - that Mr Tomlinson's Inquiry will now come within the QCA's remit. Looking at curriculum change without also considering exams and qualifications will cause problems in the future.

"Now is a prime opportunity to set about ensuring that the whole exams and qualifications system is simplified, so that it supports the curriculum and not the other way around. I hope the department are brave enough to take that bold step."

The other seven recruits to the QCA board include education consultant Jim Rose, vice chancellor of Brighton University Sir David Watson, and two school principals.

Mike Beasley, the former managing director at Jaguar, chairman of Data Connection Ian Ferguson and Unilever chairman Richard Greenhalgh were also appointed.

"QCA has an important and challenging agenda," said education secretary Charles Clarke.

"It needs a strong board to provide the strategic direction necessary for successful delivery. I am pleased to make these appointments and I am confident the new members will make a major contribution."
