The Telegraph has a little thing that you can play with today where you can check the division of public spending by year since 1955 by allocation. Based on IFS data.
Newsflash - Reeves is pretty much dividing budgets like all her predecessors, Labour and Conservative did. Very little difference except New Labour put more into education and policing than other governments.
Reeves’s problem is that her party cannot accept the case for any cuts. None. So she has very little headroom to spend anything more on areas where needs are increasing. Those areas are health and welfare and directly about productivity. So her attitude is probably approved by the City, but my criticism of her is lack of political nous. She is right on the economics, but she is totally wrong in terms of bringing her colleagues along with her. Good economic choices are not necessarily political ones
