Sir Keir Starmer has been forced to deny he is ‘plotting a war against middle Britain’ amid backlash over expected tax hikes in the Budget and claims he will betray Labour’s manifesto pledge not to raise taxes for ‘working people’.Labour had previously promised not to increase taxes on what it described as ‘working people,’ explicitly ruling out a rise on VAT, national insurance, and income tax.There is rising speculation however he could increase the burden for those who have income from shares and property. When asked to define the term during a broadcast interview in Samoa, Sir Keir said it was someone who ‘goes out and earns their living, usually paid in a sort of monthly cheque’ and who cannot ‘write a cheque to get out of difficulties’.He was again pressed on the issue at a media conference today coinciding with the end of the Commonwealth heads of government meeting (Chogm) in Samoa.Sky News political editor Beth Rigby asked the Prime Minister whether he was ‘plotting a war on middle Britain’.

We have to deal with that.’In the past, for the last 14 years, leaders have walked past those problems, created fictions, and I’m not prepared to do that.’We’re going to fix the foundations and having fixed the foundations we’re going to rebuild our country. ‘That is a very clear plan to ensure people are better off, living standards go up wherever they live across the United Kingdom  and make sure the NHS is not just back on its feet, but fit for the future and to ensure we’ve got the public services the public are entitled to and deserve.’That’s my focus, that’s why I came into politics and that is the mission of this government.’ Asked whether he had misled the public in the Labour manifesto, the Prime Minister responded: ‘No, we were very clear about the tax rises that we would necessarily have to make, whatever the circumstances, and you’ve listed them there, and I listed them, I don’t know how many times in the campaign.’We were equally clear in the manifesto and in the campaign that we wouldn’t be increasing taxes on working people, and spelt out what we meant by that in terms of income tax, in terms of NICs and in terms of VAT and we intend to keep the promises that we made in our manifesto.’It comes after the Prime Minister told Sky News he does not consider people who have an income from assets such as shares of property to be working people, paving the way for potential tax rises.’They wouldn’t come within my definition,’ he said.In a partial climbdown on Sir Keir’s position, Downing Street clarified on Friday that those who hold a small amount of savings in stocks and shares still count as working people.
