Nick Clegg has said that the Budget is one the biggest questions facing politicians at the moment and that: "compassionate Conservativism is dead or dying."
Speaking on The Agenda with Tom Bradby, the Deputy Prime Minister said:
One of the big question for all politicians my party included to explain is as you have to carry on balancing the books of whoever is in power - how do you do that as fairly as possible?
The Conservatives have taken really quite a radical approach. ..They have said they won't ask anyone for a single extra penny in tax to start balancing the books. The only people who will pay the extra burden to fill the black hole in the public finances are the working age poor and the public services they rely on. Now I think that is socially unsustainable and it's very difficult to justify and it doesn't make much economic sense either.
Other guests on tonight’s programme are comedian Dom Joly, broadcaster and columnist Julia Hartley-Brewer and novelist Nikita Lalwani.
The Agenda with Tom Bradby to be broadcast on ITV at 10.35pm tonight.

Nick Clegg has warned his party that the war on drugs "is not working".
"Treat the people with addictions in the way that they need to be dealt with, which is they need help," he told the Lib Dem conference.
"If you really want to be tough on the Mr Bigs, don't do what we're doing at the moment which is imprisoning hundreds of people for personal possession," Clegg said.
"What happens? They end up getting hooked on harder drugs, they end up hanging out with hardened criminals and they end up coming out as either criminals who inflict further misery on other victims or become even more hapless victims of the criminal gangs."
"How idiotic is that?" the Lib Dem leader added.
Nick Clegg has said the Lib Dems should "aspire to deliver home rule to Wales" when it is delivered in Scotland.
"When we will, and we will - no ifs and no buts ... when we deliver what is in effect home rule here to Scotland within the United Kingdom I think we should aspire to deliver home rule to Wales as well."
Liberal Democrat leader Nick Clegg has reiterated his unease over the issue of assisted dying.
"This is something of such profound personal conscience and personally I am not persuaded it is sensible for the state to seek to capture in legislation decisions," Clegg told a Question and Answer session at the party's annual conference.
"I'm personally quite sceptical about the ability to capture what is a very, very difficult decision about when you endorse under the law the taking of someone's life," he told delegates.
"I'm not persuaded but I totally accept this is something which does need to be debated, calmly and sincerely," he added.
Nick Clegg has told the Liberal Democrat conference his party is prepared to take some "uncomfortable decisions" to secure the long-term future.
The Lib Dem leader said: "That's what all these difficult, gory, unpopular decisions around the deficit are about.
"They're all about making sure that we clear the decks, wipe the slate clean for the next generation."
A railway line through the "brain-belt of Britain" will be built to serve new garden cities, Nick Clegg has announced.
Stations along the express route from Oxford to Cambridge will be granted to up to five towns that agree to build between 9,000 and 15,000 homes, the Deputy Prime Minister said.
Britain faces a housing crisis. Garden cities are a vital cornerstone of our plan to boost house building to 300,000 homes a year - enough to meet demand and keep prices in reach - while still protecting our precious green space and preventing urban sprawl. Our plan is to build a series of high quality new towns and cities where people want to live, with green space, sustainable transport and spacious homes.
The Conservatives have held back the development of garden cities on the scale necessary, but if Liberal Democrats are part of the next government, we will ensure at least 10 get under way - with up to five along this new Garden Cities Railway, bringing new homes and jobs to the brain-belt of South East England.
Nick Clegg has said the Conservatives and Labour are presenting the British public with a "dismal choice" at the next general election.
"Those choices, either sticking your head in the sand or beating up on the poor are not the choices the British people want," the Deputy Prime Minister told BBC's The Andrew Marr Show.
"They want balance between a stronger economy and a fairer society and that is what we're offering," the Lib Dem leader said.
Nick Clegg has said the Islamic State is "a challenge and threat" following the murder of British hostage Alan Henning.
Speaking on BBC's The Andrew Marr Show, the Deputy Prime Minister said it was "a very serious threat to our way of life that will last a very long period of time."
Disagreeing with comments made by former Chief of Defence Staff General Lord Richards, Clegg said, "I don't think it's a question of ramping up conventional armed forces again as if we were fighting state-to-state conflicts."
Nick Clegg said "of course we can" when asked if he could turn round the Lib Dems' fortunes before the General Election.
Clegg spoke as he arrived at the Lib Dem conference in Glasgow.
He posed with Baroness Sal Brinton, former MEP Liz Lynne, Linda Jack and Daisy Cooper - the four candidates vying to succeed Tim Farron as party president.
