The Democratic Unionist Party and Sinn Féin have clashed over looming spending cuts in Northern Ireland.
Senior teachers have warned jobs could be lost after Northern Ireland Secretary James Brokenshire published indicative figures for a budget he would pass if Stormont's warring parties do not reach a deal.
The DUP accused republicans of collapsing devolved power-sharing in January to avoid making unpopular decisions.
Sinn Féin leader at Stormont Michelle O'Neill lambasted the Tories for "savage" spending reductions and accepted difficult choices lay ahead.
Outgoing East Antrim DUP MP Sammy Wilson said: "Sinn Féin brought down the Assembly, not over Renewable Heat Incentive, but due to their desire to avoid making any unpopular decisions.
"That makes them not fit for government then, and if they continue that mind-set, not likely to want to be in government now."
He accused former Sinn Féin finance minister Máirtín Ó Muilleoir of dodging decisions last year and never presenting a draft budget to his Stormont counterparts.
Politicians will decide on Thursday whether to halt talks to restore power-sharing until the British general election is over in June.
Mr Brokenshire said he had taken advice on his draft budget proposal from civil servants in Northern Ireland and sought to reflect the priorities of the local parties before the Assembly was dissolved in January.
It includes nearly £42m of unallocated funding for day to day spending.
A proposed 2.5% cut would equate to a loss of £50m for education.
Mrs O'Neill blamed "big difficult" decisions to come on the Tory government deciding to attack public services, including the NHS and education.
"We will be very up front about it, the cuts to public services as a result of the Tories are going to be extremely difficult, but there's a pie and whenever departments are allocated their funding it is up to individual ministers to take decisions."
She added: "The Tory cuts to public services have been ongoing, consistent and savage since 2010 when they came into power - so we had difficult decisions and will always have difficult decisions to contend with."
