Northern Ireland parties have set out their position on the reform of MPs' expenses and allowances ahead of a vote in the House of Commons.
DUP and UUP MPs have backed government plans to reform the system of parliamentary expenses and allowances.
Gordon Brown has urged MPs to support the reforms, despite having dropped the main proposal for a daily allowance.
Plans were passed to stop claims by London MPs for second homes, for receipts to back up all claims and to publish details of second job payments.
The DUP said whatever is agreed must have public support. Sinn Fein said its MPs must not be discriminated against.
Despite concerns raised during a four-hour debate, MPs agreed to make Commons authorities responsible for employing their workers, subject to a review.
The SDLP said reforms should be based on an independent review. The UUP have been critical of some of the proposals.
Mr Brown said they were the "biggest changes in 25 years" to expenses.
SDLP South Belfast MP Alasdair McDonnell said: "I believe the inquiry undertaken by Sir Christopher Kelly should be allowed to follow through and, if amendments are needed, let him make the amendments having consulted on it."
All changes are temporary, as they come ahead of a more thorough review of MPs' expenses by Sir Christopher Kelly's Committee on Standards in Public Life - which will publish its findings later this year.
DUP East Londonderry MP Gregory Campbell said "clarity" was needed.
"Our intention is to vote for transparency and clarity whatever the propositions are and however they are amended."
On Wednesday Gordon Brown outlined the issues that would be in the government's motion on Thursday, on demanding receipts for all claims and stopping MPs with constituencies near Parliament claiming for second homes.
"Other proposals are for the House of Commons - rather than MPs - to be responsible for employing their staff."
