The Sunday Times (p1) led its report on claims that divisions in prime minister John Major's cabinet have deepened with a new row over teacher's pay.
Chancellor Kenneth Clarke and treasury secretary Jonathan Aitken clashed at last week's cabinet meeting over the chancellor's refusal to fund the 2.7% award, the paper said.
Mr Aitken backed education secretary Gillian Shepherd in her bid for extra money.
Governors, faced with the prospect of sacking thousands of teachers, reacted with dismay.
The Sunday Telegraph (page 3) reported that the no-strike Professional Association of Teachers will this week press Mrs Shephard to raise the cap on local authorities and overhaul the school funding system.
Parents, governors and teachers from 20 education authorities were also meeting this weekend to inaugurate Fight Against the Cuts in Education and to plan a mass rally for 25 March.
But the paper described the threat from headteachers as most serious.
The Secondary Heads Association has decided to ask the department for education to specify the minimum classroom space considered safe for each child.
It will then recommend that members enforce it, by sending children home if necessary.
