Will the UK's plan for defence help it hit Nato's spending target?

When he resigned on 11 June, former Defence Secretary John Healey said that the DIP he had been presented with only committed to take Nato-qualifying defence spending to 2.68% by 2030. He said this was insufficient "to defend the country at this time of rising threats" and the government should be committing 3% of GDP to defence by 2030 rather than in the next parliament. The actual DIP says that "based on latest projections" UK defence spending will rise to 2.7% of GDP by 2027-28. It does not provide a year-by-year estimate for later years but states that the money spent on defence "by the end of the decade will be 2.7% of GDP". That suggests that the proportion of GDP spent on defence is not planned to change between 2027 and 2030 That 2.7% figure suggests an increase on the original DIP of around 0.02% of GDP, which the government has found since Healey resigned - that's equivalent in today's money to £600m extra in 2030. Healey posted on X after the DIP was published on Tuesday that a "target date" was needed to achieve the 3% target and a "clear plan" for how the UK gets to Nato's 3.5% of GDP by 2035.
