UK PM Burnham faces a significant deterioration in the public finances that will leave him needing to find about GBP 10bln in either tax rises or spending cuts in his first budget, according to The Times's Swinford

The operative distinction is between consolidation done through tax rises, which tends to be received as growth-negative but issuance-neutral, and consolidation done through spending restraint, which has historically been harder to deliver and slower to verify. The figure cited is modest relative to past UK fiscal events; what moves the long end in episodes of this kind is whether the headroom against the fiscal rules is being rebuilt or merely met, since thin headroom has repeatedly left the budget hostage to small forecast revisions at the next OBR round. The tells are the Debt Management Office remit, any sign of a rules rewrite, and whether briefing shifts from totals to specific measures. Political capital of a new premier matters here: early budgets are when consolidation is easiest to pass and most often attempted.
