ITV News' Political Correspondent Romilly Weeks heard from those in favour of the cap and those against:
The Government is likely to win a vote this evening on a bill to cap benefit rises, but today's debate in the House of Commons was one they were desperate to win.
The issue, they believe, puts Labour on the side of the unemployed and the benefit claimants, instead of those in work whose pay has risen little.
ITV News' Political Editor Tom Bradby reports:
The Shadow Work and Pensions Secretary Liam Byrne is tweeting about tonight's vote on a bill to cap benefits rises.
Best way to make sure working peoples' income rise faster than benefits is to protect tax credits and this striverstax hits tax credits hardFrom @LiamByrneMP on Twitter:
Our vote tonight is a defence of workers - and their incomes.From @LiamByrneMP on Twitter:
The Lib Dem Business Secretary Vince Cable has said he is "uncomfortable" with some of his Tory coalition colleagues referring to the unemployed as "skivers".
He said that people who are out of work should be treated with "dignity" while accepting that the economic situation necessitates a "squeeze on the welfare budget".
ITV News' Political Correspondent Libby Wiener asked him whether he is comfortable supporting the benefits cap:
The Labour MP David Miliband has made an impassioned speech in the House of Commons opposing the benefits cap.
He accuses the coalition of proposing savings of £1.1bn from the richest in society, compared with £5.6bn from those on benefits and tax credits.

This rancid Bill is not about fairness or affordability.
It reeks of politics, the politics of dividing lines that the current Government spent so much time denouncing when they were in Opposition in the dog days of the Brown Administration.
It says a lot that within two years it has fallen into the same trap.
The Liberal Democrat MP for Torbay, Adrian Sanders, has said he will abstain from tonight's vote on a bill to cap benefits.
To be clear,I'll abstain tonight,but vote against at 3rd reading if I can't support an amendment at committee stageFrom @adriansandersmp on Twitter:

Labour MPs both in the Commons and on Twitter are attacking the coalition's benefit plans for "adversely affecting" disabled people.
Disabled people feel misled by Osborne who said their benefit would be protectedFrom @jowellt on Twitter:
Disability Rights UK say 1m disabled people will be adversely affected by 1% cap. Tories/LDs not interested & not listeningFrom @PatGlassMP on Twitter:
The Work and Pensions Secretary Iain Duncan Smith has attacked Labour's job creation record, accusing it of spending taxpayers' money like "drunks on a Friday night".

Today’s Bill is bad news for people living in poverty, whether they’re in work or out of work. Clearly, there are difficult decisions to be taken by Government, but Ministers’ opportunistic rhetoric on this issue is disturbing. Allowing today’s Bill to be presented as a choice between the ‘deserving and ‘underserving poor’ is both morally and economically wrong.
As incomes fall and costs rise for people – whether they are in or out of work - we are at risk of entering a decade of destitution.
Deputy Prime Minister Nick Clegg has defended plans for a three-year benefits squeeze as he faced party dissent among his own MPs ahead of a key Commons vote.
In Commons clashes ahead of the debate - deputy Labour leader Harriet Harman said the Government had "failed on compassion".
But Mr Clegg questioned why the Opposition supported a 1% pay rise cap for public sector workers but not the curb on benefit payments and where it would find the savings.
