Employment Relations Minister Jo Swinson has said the present salary level for MPs is "absolutely adequate".
Amid reports that a pay rise of up to £7,500 is under consideration by the Independent Parliamentary Standards Authority, she told the BBC: "I have no problems whatsoever with my salary".
Ms Swinson also said it was right that the "bad old days" of MPs setting their own pay had been ended but cautioned Ipsa that it had to take account of public sector pay curbs.
"I hope that the Independent Parliamentary Standards Authority have looked in detail at all of the relevant issues to put this into context".
In January, a report by the Independent Parliamentary Standards Authority on its initial consultation into pay and pensions found:
- In an anonymous survey, MPs suggested a 32% pay increase to the body charged with regulating pay and benefits.
- 27% of the MPs wanted their pay to go up by more than 1% over the next two years - despite public sector rises and most working age benefits being capped at that level.

MPs are already very well paid both in terms of European politicians and the average salary in this country.
It would be particularly egregious for politicians to be handed a whopping great pay rise while hard-pressed taxpayers tighten their own belts.
Ipsa must recognise that its own polling shows the public simply do not support an increase, nor would it be consistent for MPs to take a rise while rightly freezing pay elsewhere in the public sector.
The Prime Minister has urged the Independent Parliamentary Standards Authority (Ipsa) to "show restraint" amid reports that the body is considering a pay rise for MPs of around £7,500.
David Cameron said he did not know what the regulator would recommend but: "Whatever Ipsa recommends we can't see the cost of politics or Westminster going up."
"We should see the cost of Westminster go down. Anything would be unthinkable unless the cost of politics was frozen and cut, so I'll wait and see what Ipsa have to say.
"What I said to Ipsa was that restraint is necessary, he added.
The Independent Parliamentary Standards Authority (Ipsa) is reportedly considering setting a pay rise for MPs of around £7,500, taking their salary to £75,000.
Ipsa, which is charged with regulating MPs' pay and benefits, is set to announce the rise on July 11, the Sun on Sunday reported.
Meanwhile, the Mail on Sunday said sources indicated the regulator would suggest raising MPs' pay, in a series of upratings starting in 2015, coupled with much higher pension contributions.
The Prime Minister has urged the body to "show restraint" and said it would be "unthinkable" to make Westminster more expensive to the taxpayer.
