The report on Baroness Warsi finds she did breach the ministerial code but it "was a minor one" and "did not use her office for personal financial gain".
The Prime Minister accepts it was a minor breach of the ministerial code and calls Baroness Warsi "a great asset".
Responding to the report, Baroness Warsi said: "The allegations on this matter were untrue and unsubstantiated and I am pleased that Sir Alex Allan’s report has confirmed that."
Baroness Warsi still faces investigation by the Lords Commissioner on Standards on her expenses, so she's not totally in the clear yet.
