The president of the NASUWT teaching union is set to attack the government's education reforms, claiming they are distracting from the task of teaching children.
Mick Lyons will tell NASUWT's annual conference in Bournemouth hat education is being used as a "political football".
In a speech, he will say: "Daily denigration of the work and commitment of teachers, false claims of plummeting educational standards, and attacks on jobs, salaries, conditions of service and pensions are leaving colleagues heartily sickened and demoralised."
