Fresh allegations have been made about the expense claims of Communities Minister Shahid Malik.
Gordon Brown has denied he acted too quickly in bringing Shahid Malik back into government, following new allegations about the MP's expenses.
The accusations relate to reports that he claimed for the costs of two sets of office space. Mr Malik says the allegations are "complete fabrication".
Mr Brown said the communities minister was cleared by watchdog Sir Philip Mawer of breaching the ministerial code over the first set of allegations.
They come after he was cleared of breaching the ministerial code over housing arrangements.
And he would be answerable to independent auditors - like all other MPs - over any further allegations.
No 10 has not responded directly to the new claims but says Mr Malik has not broken the ministerial code.
Mr Malik denies a Daily Telegraph story about claiming for two offices.
The Cabinet Office has published the report by the independent advisor on the ministerial code into allegations published by the Daily Telegraph on 15 May.
These claimed Mr Malik had benefited from rent at a preferential rate on both his office and home in Dewsbury.
Sir Philip Mawer found Mr Malik had not breached the ministerial code because the rent said to have been charged was reasonable in the light of market and other commercial considerations.
But Mr Malik has been asked to put his rental arrangements for the property in Dewsbury, West Yorkshire on a more formal basis, with a tenancy agreement that specifies the rent to be paid, and for paying all of his rent in future by direct debit.
Second office
Sir Philip Mawer said it was unfortunate Mr Malik had been unable to provide a proper audit trail from the start.
BBC political correspondent Jo Coburn said Mr Malik has written to the prime minister to confirm he has already provided an audit trial.
But now there are fresh allegations in the Telegraph about expenses relating to claims for a second office alongside his taxpayer funded constituency office.
Mr Malik has admitted he does have a second office which he says is entirely within the rules and the agreement was lodged with the House authorities.
He vigorously denies claiming anything from the public purse for his main designated home in the constituency.
