Tony Blair's attempts to win over rebels opposed to school reforms received a mixed reception as opponents prepared for a public meeting in Birmingham tonight.
Labour MP Richard Burden (Northfield) will speak at the event at the Council House, which will be chaired by Sir Albert Bore, leader of the Labour group on the city council.
Mr Burden is one of the backbenchers opposed to Government's Education White Paper, which includes proposals to create independent "trust schools" free from local authority control.
But Sir Albert said he had been reassured by compromise proposals put forward by Ruth Kelly, the Education Secretary, which would allow councils to play a limited role in running schools.
The event has been organised by Compass, a left-wing pressure group which published an "alternative white paper" criticising the Government's policies last year.
The document was backed by MPs including Mr Burden, Lynne Jones (Lab Selly Oak) and Clare Short (Lab Lady-wood), as well as Estelle Morris, the former MP for Yardley in Birmingham and former Education Secretary.
It also has the backing of Neil Kinnock, the former Labour leader.
Last week Ministers delayed the long-awaited publication of the Education Bill which will be put before the House of Commons, apparently due to concern the plans had still not won the backing of MPs.
Christine Blower, deputy general secretary of the National Union of Teachers, will also attend the event.
Mr Burden said: "We now wait to see what the Bill contains when it is published.
"I will be looking for some specific changes to what is in the White Paper, including on admissions procedure, and the right of local authorities to set up schools."
