Reeves braced for OBR forecasts to blow £20bn hole in tax and spending plans

Downgrades by Treasury watchdog could force chancellor to raise taxes or cut spending at budget to meet fiscal rules

Rachel Reeves is braced for revised forecasts by the Office for Budget Responsibility (OBR) to blow a 20bn hole in her tax and spending plans before the autumn budget.

Even without changing the totals the chancellor set out in her spending review on Wednesday, a weaker forecast from the the Treasury's independent watchdog could force her to find significantly more money at the budget to meet her non-negotiable" fiscal rules.
