POLITICIANS from all parties have condemned proposals to give MPs a huge salary hike – but the pay rise could still go ahead.

At a time when much of the country is suffering financially, David Cameron, Ed Miliband and Nick Clegg warned that it would be wrong to give MPs an extra £7000 a year.

The Labour and Liberal Democrat leaders even pledged not to take the cash, although the Prime Minister stopped short of making that commitment.

However, the body in charge of salaries, the Independent Parliamentary Standards Authority (Ipsa), remained defiant and said MPs' pay had to catch up with other professions and international benchmarks.

Any rise in MPs' pay could also have a knock-on effect at Holyrood, as it helps determine how much MSPs earn.

Polls suggest the majority of the public is opposed to any pay rise for MPs.

Under the IPSA plans salaries would rise by 11% from £66,396 to £74,000 a year, costing taxpayers an extra £4.6 million a year, when national insurance is included.

However, at the same time MPs' generous pensions and "golden goodbyes" would be cut, alongside expenses for dinners, TV licences and taxis.

The proposals would not take effect until 2015, after the next general election.

Supporters of a rise argue the job of an MP is increasingly the preserve of the privileged and the well-off.

However, critics warn MPs should not get a large hike when other public servants are seeing their wages fall in real terms.

His view was echoed by Mr Miliband, who said: "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."

He said he would not take the extra cash.

His team said the labour leader was sure "the package should not go ahead, full stop".

Mr Clegg also said he would not take the extra money but hinted other LibDem MPs might, saying he was luckier than many others because he also has a ministerial salary.

Downing Street refused to say if the Prime Minister would accept the increase, saying there would be a consultation before the regulator reached a final decision.

But a Number 10 spokesman added: "The cost of politics should go down, not up. And MPs' pay shouldn't go up while public sector pay is rightly being constrained."

The proposals were also condemned by First Minister Alex Salmond, who said pay for both MPs and MSPs "should not rise beyond the limits of the restraints currently placed on public sector pay".

He added: "It is ludicrous to suggest parliamentarians should be given anything beyond these norms at a time when public sector workers are having to make do with much, much lower pay increases,.

The Scottish Government is understood to be confident there will be no increase in the pay of MSPs even if wages for MPs rise.

The Scottish Parliament voted in 2002 to link MSP salaries to those of MPs, setting the rate at 87.5%. MSPs currently earn £58,097 a year.

A Holyrood spokesman said: "This IPSA consultation exercise on Westminster MPs pay will run until October. When IPSA makes its final recommendations, then it will be a matter for the Scottish Parliament Corporate Body (SPCB) to consider and consult with all political parties and make a recommendation to the Parliament."

Meanwhile, one MP, Conservative Charles Walker, attacked party leaders for politicising the issue and demanded that they live on a backbencher's salary.

However, RMT union boss Bob Crow said his members would also be fighting for an 11% pay rise if the plans went ahead.
