Why breaking his tax pledge probably won't harm Boris Johnson

Boris Johnson's announcement today of how he will fix the £15 billion hole in health and social care may well be the decision that determines his and his party's fate at the next election, for better or worse - and, by implication, Keir Starmer's reaction will also determine his destiny. Probably the most important point is that after the 18 months we've had, most people would argue that putting the NHS and care for the elderly and vulnerable on a stable financial footing should be the prime minister's number one priority. Johnson's critics would say he shouldn't break two important manifesto pledges - not to raise national insurance, and not to ignore the earnings index to set the state pension - to pay for it. And they would also say that increasing national insurance by 1.25% to garner an extra £10 billion plus per year is an unfair tax choice, with its burden falling disproportionately on younger, poorer people and employers. So, putting to one side the more important question of whether the policy is good or bad for the UK - and I will assess that when I have the fine print - will it be good or bad for Boris Johnson and the Tory Party?

I suspect, despite the bellyaching of his Cabinet ministers and backbenchers, it will turn out to be good for him. Because: 1) Of all the reasons for paying more tax, doing so to fix health and social care is one policy that British people will probably feel okay about. 2) Raising the money through national insurance rather than income tax means it automatically applies throughout the whole UK, including Scotland - and for Tory unionists, this is a virtue, in that it will almost certainly lead to a punch up with the SNP.

3) Literally no one expects Johnson to keep his promises (in just recent months he's broken them on the overseas aid budget and having vaccine passports); his brand is not as a man of his word. 4) If Labour votes against the national insurance rise, Johnson will taunt Starmer all the way to the next election with having voted against supporting health and social care. 5) As I mentioned yesterday, his Tory base (and more Labour supporters than will be prepared to admit it) will approve of a policy that protects at least £100,000 of their savings from social care costs. Johnson's estranged adviser, Dominic Cummings thinks this will be the moment of Johnson's downfall, that breaking his word by raising taxes will sink him as it sunk George Bush Snr in the 1990s. On this, I fear Cummings - who is intent on bringing about what he calls regime change - is succumbing to wishful thinking.

At worst for Johnson, voters will think "same old Boris, never could trust him"; at best they'll say "fixing health and social care are what we want".
