Mr Blair and Education Secretary Ruth Kelly are holding a seminar at Downing Street for 50 schools, businesses and other groups interested in the plans.
The prime minister's spokesman said he was struck "by how united the cabinet was" in its discussion of the reforms.
Potential Labour rebels say they still have concerns about the details. <!-- E SF -->
But the seminar at No 10 will be seen as a clear signal Mr Blair wants to push ahead with plans to involve new external partners - companies, faith groups, charities - in setting up and running the schools.
The seminar, similar to one held at the education department last week, is for organisations wanting to form or take part in trust schools.
Among those at the seminar are accountants KPMG, Monkseaton Language College, Deacon's School in Cambridgeshire, Thomas Telford School in Shropshire, and the University of the West of England.Continued At Source
