The three MPs facing criminal charges over their expenses could still receive tens of thousands of pounds in "golden goodbyes" on stepping down from the Commons, it has emerged.
Elliot Morley, Jim Devine and David Chaytor are likely to get the payments because they will still be "innocent until proven guilty" by the time of the general election.
All three Labour MPs deny allegations of false accounting, and have pledged to defend themselves "robustly".
Legal advisers to Speaker John Bercow are understood to have been examining whether the resettlement grants could be withheld or delayed while the court process is completed. However, they have yet to find a way that satisfies "natural justice" as the men have not been convicted of any crime.
MPs are entitled to payoffs of up to £65,000 when they leave Parliament at an election, depending on their age and length of service.

Aides to David Cameron said he was "disgusted" by the idea, while Lib Dem leader Nick Clegg said the public would be "appalled".
The parties were also ramping up their wider battle to be seen as the toughest on political sleaze.
