Rachel Reeves' spending plans have already been thrown into chaos today after figures showed the economy tumbling into the red.
GDP was down 0.3 per cent in April, worse than analysts had expected, and raising more questions about the realism of the Chancellor's splurge on services.
Although UK plc has still grown over the past three months, evidence has been mounting of a slowdown. Ms Reeves admitted the data - which coincide with the huge national insurance tax raid on businesses taking effect - were 'disappointing'.
In a round of broadcast interviews, she pointed the finger at 'uncertainty' surrounding Donald Trump's trade tariffs.
But Ms Reeves again avoided ruling out more tax increases at the Autumn Budget, instead arguing that the plans she laid out yesterday - based on healthier economic forecasts - were 'fully funded'.
