Daily Mail columnist Guy Adams spent a day at the City of London trading floor of IG Group, watching how financial markets reacted to Prime Minister Andy Burnham's first Commons speech, in which he outlined a Left-wing economic vision involving greater state control and protection of public spending. While Burnham's remarks were well received by Labour MPs in Parliament, they triggered immediate unease among traders, with bond yields spiking as the speech was delivered — illustrating a direct clash between the government's spending ambitions and market confidence in the UK's fiscal position.

The piece lays out the scale of Britain's fiscal challenge: the government spends £1,368billion a year but raises only £1,235billion in tax, leaving a £133billion deficit that must be covered by borrowing, on top of national debt exceeding £3trillion. Debt interest payments alone cost £130billion last year, more than double the defence budget. The yield on 30-year gilts rose from 5.7% to 5.94% over the course of the week — the highest level since 1998 — having already climbed from 4.6% when Labour took office in 2024, reflecting investors' growing wariness about the sustainability of UK government borrowing.
