Phil Hope will be hoping his decision to repay his past five years expenses claims will protect his career as an MP.
The 41,709 he will repay is the biggest amount an MP has paid back since the debate unfolded.
Mr Hope says he made the decision with his family because the public anger has been a "massive blow" to perceptions of his integrity.
But some voters say he is only giving back the money in an attempt to keep his seat – he won the last General Election with a majority of just 1,517 votes.

Political experts have given their views about the decision.
Stephen Parsons, a politics lecturer at De Montfort University in Leicester, said: "It would not surprise me at all if MPs have been told it would look a lot better if they did something to pay back some of their expenses. But I think Gordon Brown left it a bit late to lean on them because David Cameron did it first and now it would look like he was just following in his footsteps.
"I think it is more likely to be a case of Mr Hope realising this is looking really bad and that it might be in his interest to repay it."
What is certain is that public outrage was instrumental in forcing Mr Hope's hand.
It is not often that "people power" can have such an impact on Parliament.
The last time it was seen on such a large scale was during the petrol protests in 2000 and before that, the poll tax revolt.
So is the strength of feeling about MPs' expenses as powerful?
Dr Parsons said: "In some ways this is even stronger than that because people have not even had to march or hold demonstrations.
"It has reminded me of the last days of the Major Government. There was a sense then that their behaviour was just not acceptable and verging into illegal.
"When people are in power for too long it can get very corrupt and people get very concerned about the ethical conduct of MPs.
"This has come about from a request through the Freedom of Information
Act. Many MPs were opposed to it and some tried to get it thrown out.
"There is very much a sense of outrage about what they have claimed for and there is a perception that this really is not on.
"MPs regulating themselves is probably not a very good thing to be happening and people are saying it needs to be sorted out.
"I think it will lead to a major shift in the way MPs conduct their business."
Dr Glyn Daly, who teaches politics at the University of Northampton, agrees the wave of public feeling and its consequences for our MPs is unprecedented.
He said the debate that has unfolded could bring about a major change in the way MPs are held accountable.
Dr Daly said: "I think it is very significant. At a time of economic downturn, the public have an absolute right to expect great moral leadership and moral accountability from our democratic leaders.
The public's anger at this is fully justified.
"After all this is something that does affect us all. It is not something we can just put behind us and simply say 'It's one rule for them and another for the rest of us'.
"People are realising that the whole standing of politics and political leadership in this country is simply without credibility unless they address this issue. They cannot think this situation is simply going to go away with a few MPs falling on their swords.
"It needs to be addressed and I would certainly favour a system of rental allowance or even better, why not social housing for MPs?"
