Cabinet Minister Baroness Warsi has been cleared of wrongly claiming expenses after a House of Lords investigation.
House of Lords Standards Commissioner Paul Kernaghan looked into allegations that Lady Warsi claimed for accommodation expenses while staying at a friend's house rent-free.
The minister said she was "delighted" to draw a line under the matter and David Cameron said it cleared the way for her to lead the Tory campaign for elected police commissioners later this year.
Last month, the Prime Minister's adviser on ministerial interests Sir Alex Allan found her guilty of a "minor" breach of the ministerial code in relation to a separate claim about taking a business partner with her on an official trip to Pakistan.
In her statement on Thursday, Lady Warsi said: "I believe that being a member of the House of Lords is a privilege and I take that privilege seriously.
"I have always maintained that the allegations surrounding my expenses were untrue and I am delighted that Sir Paul Kernaghan has dismissed them.
"His report and the report by Sir Alex Allan - two independent inquiries - have now drawn a line under these matters and my only focus now will be to get on with my job."
The Prime Minister added: "I am pleased that these allegations have been dismissed by the Lords Commissioner.
"With elections for Police and Crime Commissioners in the autumn, this will be a big summer of campaigning for the Conservative Party. As Co-Chairman, Sayeeda will be leading that campaign"
