MPs' pay should be increased by £6,000 to £74,000 a year from 2015, the Commons expenses watchdog has said.
But the Independent Parliamentary Standards Authority (Ipsa)
also recommends cuts to perks such as meal allowances and taxis and a
less generous pension scheme.And "golden goodbyes" paid to retiring MPs could also be trimmed.
The plan has been condemned by party leaders and some MPs who say Ipsa should go back to the drawing board.
The watchdog is to consult on the rise but MPs can not block it because they handed control of the decision to the independent body in the wake of the 2009 expenses scandal.
A Downing Street spokesman said: "The cost of politics should go down not up. And MPs' pay shouldn't go up while public sector pay is, rightly, being constrained."
Deputy Prime Minister Nick Clegg, who has said he will not take the increase, said it was "about the worst time to advocate a double digit pay increase for MPs," adding that the public would find it "incomprehensible".
'Fixes and fudges' Labour leader Ed Miliband said he did not believe the rise should go ahead - and confirmed he would not take it if it did, but he said he was confident Ipsa would change its recommendation after a public backlash.
"I don't think MPs should be getting a 10% pay rise when nurses and teachers are facing either pay freezes or very low increases and people in the private sector are facing similar circumstances," said Mr Miliband.
Prime Minister David Cameron has criticised the proposed increase but a No 10 source declined to comment on whether he would be taking it. Pressed on the question, the PM's spokesman said: "It's not a pay rise. It's a proposal".
He pointed out the IPSA package was still to go out to consultation and Downing Street would be submitting its own response.
The Ipsa proposals include:
- A salary of £74,000 in 2015, with rises after that linked to average earnings across the whole economy
- A new pension on a par with other parts of the public sector, moving from a final salary to career average scheme, which Ipsa says will save taxpayers nearly £2.5m a year
- Scrapping "resettlement payments", which were worth up to £64,766 for long-serving MPs still of a working age, the first £30,000 of which was tax-free. and introducing "more modest" redundancy packages, available only to those who contest their seat and lose
- A "tighter regime" of business costs and expenses - including an end to the £15 a night meal allowance and taxis home after late sittings
"For the first time, an independent body will decide what MPs should receive. We will do so in full view, and after consultation with the public."
'Obscene' Sir Ian told BBC Radio 5 Live MPs should be treated like "modern professionals" and part of the package was a "radical proposal" to introduce an annual "report card" to show the public what MPs did for their money.
