The first signs of internal disquiet towards Brown's policies surfaced in May 2008. The 2007 budgethis last as Chancellorabolished the 10% income tax rate for the lowest earners (5.1 million people), increasing their rate to the next highest, 20%. Earners who fell within the 22% tax rate band had their rate reduced to 20%, and tax allowances were also made for over-65s. These measures came into effect in April 2008. The "10p tax rate cut" as it was commonly referred to, was sharply criticised by Frank Field and several other backbenchers. Field also said that Brown did not seem to be enjoying his job. Health Secretary Alan Johnson believed that Field was motivated primarily by a personal dislike of Brown, and Field later apologised, saying that he had regretted allowing his campaign to become personal. Chancellor Alistair Darling cut the tax rate for 22 million people and borrowed around £2.7 billion to reimburse those on lower and middle incomes who had suffered.
