It is possible that the Chancellor had come to a different conclusion from the PM as to which way the Maria Miller crisis was going.
The resignation of Culture Secretary following sustained pressure shows that, five years on, fury over expenses has only grown.
Maria Miller's resignation letter has been made public, along with David Cameron's response.
Many people thought that Maria Miller's resignation as Culture Secretary was inevitable, despite support for the MP from the Prime Minister and some other senior Tories.
But what has been the reaction to it all in her constituency of Basingstoke? Our reporter Cary Johnston has been finding out.
Almost two thirds of the public think David Cameron handled the Maria Miller expenses row badly, according to a new ITV News/ComRes poll.
Some 63% of those polled said the Prime Minister had performed "badly", with 32% saying he had handled the the controversy "very badly".
Just 8% of respondents said they thought Mr Cameron had dealt with it well.
ComRes polled 1,000 members of the public today.
Home Secretary Theresa May has been speaking of her disappointment at Maria Miller's resignation.
She told ITV News:
"I was very sorry to hear that Maria Miller had resigned. She has been an excellent colleague. I had worked with her on a number of issues and, as I say, I was sorry to see her leaving the cabinet."
The Department for Culture, Media and Sport has tweeted a picture of the new secretary of state, Sajid Javid, along with the department's Permanent Secretary, Sue Owen.
Mr Javid, who was previously Financial Secretary to the Treasury, will also become Equalities minister.
Following the resignation by Basingstoke MP Maria Miller as Culture Secretary, constituents have given their reaction to ITV Meridian.
The Prime Minister has told MPs he thought it was right to allow Maria Miller "the chance to get on with her job" following the controversy over her expenses claims.
Speaking during Prime Minister's Questions, David Cameron acknowledged that Ms Miller "did do something wrong" but stressed that she had apologised.
The TaxPayers' Alliance said given this response to the resignation of Maria Miller:
Maria Miller had wrongly claimed significant amounts of taxpayers’ money and her less-than-contrite apology to the Commons suggested a failure to grasp the gravity of the situation, which caused understandable public anger.
While claims for mortgage interest are no longer permitted under the new expenses regime, this episode is a stark reminder that MPs need to pay extremely careful attention when they are spending taxpayers’ money.
– Jonathan Isaby, Chief Executive of the TaxPayers' Alliance
It also underlines the need for a genuine system of recall to be introduced so that voters can hold their MP to account mid-term if they feel that they have been let down. This would be a powerful accountability mechanism to keep our elected representatives on their toes.
Sajid Javid, the MP for Bromsgrove and current financial secretary to the Treasury has been appointed as the new Culture Secretary following Maria Miller's resignation, the prime minister has said:
Sajid Javid MP is the new Secretary of State for Culture, Media, Sport and Equalities.
