Deputy leader Tom Watson says the Democratic Unionist Party shouldn’t be entitled to fund used to support opposition parties.
More than £220,000 of “Short” money is funnelled to the hard-right Ulster politicians every year so they can run a Westminster operation.
Labour deputy leader Tom Watson believed the party should surrender the perk after agreeing to prop up floundering Theresa May’s minority government.
He said: “The DUP can’t have it both ways.
“They have already secured over £1billion for Northern Ireland as part of their deal to keep the Tories in power.
“Now it turns out they’re getting more money than before from the taxpayer to oppose a government they support.
“They need to make their minds up – are they an opposition party, or are they providing Theresa May with her majority?”
