Rishi Sunak is under pressure from his own MPs to slash taxes in a sign of future trouble for the Prime Minister.
A group of 40 Conservatives has written to the Chancellor to slate his plans, arguing that the tax burden is at the highest level since the Second World War and public spending is higher than the mid 1970s.
Senior Tories including ex-Cabinet Ministers David Davis and Esther McVey penned the letter which said that constituents must be reassured that "every penny of taxpayers’ money spent on their behalf provides value for money and is not wasted".
