Expenses reform fury.
Jim Sheridan, Labour MP for Paisley and Renfrewshire North, claimed politicians would be left out of pocket and may have to "sack staff".
He said he would be urging the Independent Parliamentary Standards Authority (IPSA), set up in the wake of the expenses scandal, to reconsider their proposals.
He added: "This system is cumbersome, vindictive and it discriminates."
Labour MP David Winnick said it was "disgraceful" that MPs had to pay staff and then claim it back. He added: "It must be a nightmare for new members."
I P S A b o s s A nd re w McDonald said the new system was fair. But he added he would be willing to look at it again "if the facts change".
