Penny Mordaunt has criticised the Labour Party for "clobbering motorists" in a furious Commons rant during today's Business Questions.
She hit back at Labour's Shadow Leader of the Commons Lucy Powell after she criticised Jeremy Hunt's budget, unveiled yesterday.
Powell said: "All we got from yesterday's budget was old news briefed and leaked to the papers before it was given to parliament.
"The next time the leader cries crocodile tears for the rights of this place, she could reflect on their failure to stand by parliamentary convention and deliver budgets here first.

She added: "On the substance, the verdict is now in. The OBR forecasts that tax receipts as a proportion of GDP are set to rise to their highest level since the Second World War.
"The Resolution Foundation says the big picture has not changed. Taxes are heading up and this will be the first parliament in modern history where living standards fall to lower at the end than they were at the start."
Hitting back, Mordaunt joked that Powell is "channelling Elma Fudd this morning" - comparing the Shadow Commons Leader to a fictional character from the Looney Tunes.
She continued: "Bugs may not have been in the Chancellor's hat but support for business large and small was, help for households was, tax cuts for working people was, help for single-earner families was, and holding down the price of fuel at the pump through another fuel duty freeze was - and we will ensure that that help is handed onto consumers via pump watch.
"I'm not going take any lectures from the Labour Party on stewardship of public services and getting growth into our economy.
"No lectures on tax cutting from a Labour Party that still has £28 billion of unfunded spending commitments which can only be delivered through tax rises in its plans.
"It was the Labour Party that left office with a £71 billion black hole in the defence budget and equipment programme.
"It was Labour that brought in the fuel duty escalator and is clobbering motorists in Wales and London. It's the Labour Party in Wales that have cut the NHS budget, not once but three times in contrast to the increases we have brought in and the further 6bn we announced yesterday.
The Conservatives will preside over the first parliament in modern history to oversee a fall in living standards, a report from the Resolution Foundation has warned.
The thinktank published analysis of yesterday's Spring Budget which showed that real disposable income will drop by 0.9 per cent by next year.
It also dubbed £19 billion of cuts to public services a "fiscal fiction" and warned that the next Government will be facing a "huge" task ahead of them.
Jeremy Hunt unveiled the budget to the House of Commons yesterday, announcing a further 2p cut to national insurance.
Leaving income tax untouched, Hunt was keen to stress the benefits of the combined NI cuts announced over the last two budgets - saying it will amount to a £900 saving for the average employee.
The Chancellor also suggested National Insurance payments could be scrapped entirely, describing the levy as "particularly unfair". He said his "long-term ambition" is to end the system of double taxation.
Hunt also froze both alcohol and fuel duty until 2025, along with the creation of a "British ISA" which will allow an additional £5,000 annual investment in UK equity.
The Chancellor allocated £3.4 billion in investment aimed at improving NHS productivity, something he said will "unlock £35 billion of savings". He announced plans to get rid of the "outdated" non-dom status, instead replacing the regime with a "modern, simpler and fairer residency-based system" from April 2025.
Hunt also extended child benefits to hundreds of thousands of middle-income families, increasing the high-income child benefit charge threshold from £50,000 to £60,000.
