Two MPs say they will give away a pay rise which will boost their salary to £74,000 a year.
The pledge by Nottingham South MP Lilian Greenwood and Gedling MP Vernon Coaker comes as The Independent Parliamentary Standards Authority supported plans to give MPs an inflation-busting salary hike of ten per cent next year.
In comparison public-sector workers' pay increases have been capped at one per cent.
Ms Greenwood (Lab) said the rise was too high and she would give hers to good causes in her constituency if the rise went ahead.
"It is completely ridiculous when people up and down the country are struggling to make ends meet," she said.
"It is out of kilter with what is happening in the country.
"Most people are getting one per cent if they are lucky.
"I hope they think again about this but if they don't there are plenty of good causes in the constituency that I will use it to help."
Gedling MP Vernon Coaker (Lab) agreed.
He said: "It is an independent decision but it is unacceptable to offer MPs what they are suggesting.
"I do not want it but if it comes I will have to find something to do with it whether it is give it to charity or something like that.
"I can't accept it."
Although MPs can have their say on the amount they will be receiving, the decision will be made by The Independent Parliamentary Standards Authority.
Some believe the expenses watchdog will change its mind or be forced into a u-turn.
Nottingham East MP Chris Leslie (Lab) said: "My view is that it won't go ahead and it shouldn't go ahead.
"We are experiencing an unprecedented cost of living and it would not be right at all.
"None of the main political parties want this to go ahead.
"One of the first things that will happen after the general election will be to make sure this does not go ahead.
"If parliamentarians don't want it to happen it won't happen."
Other MPs say they do not have a view on the changes and will accept the decision that is made.
Nottingham North MP Graham Allen (Lab) said: "Nothing will happen until after the general election.
"It is all under review and what really needs to happen is a proper consultation and a review.
"MPs do not decide on this which is how it should be and I do not think MPs should have any opinion on the matter."
The only way to stop the increase, which will come into effect after May's general election, would be to change the law to abolish the watchdog.
However, the watchdog is legally bound to hold a consultation on the subject but also says the pay rise will not cost the tax payer more because there will be reductions in pensions and cuts to expenses.
Broxtowe MP Anna Soubry (Con) said: " I am not for or against it.
"For the tax payer it won't cost a single penny more.
"Under the last parliament it was agreed MPs should not have a say.
"I will wait to see if I get elected first before deciding what to spend it on."
Speaking to The Telegraph Marcial Boo, the chief executive of the Independent Parliamentary Standards Authority said: "There are lots and lots of professionals in public life and in the private sector who earn a lot more than that – so it is not an excessive amount of money at all."
