May faces fresh accusations of 'rigging Parliament'

Labour has accused the Prime Minister of running scared of an expected attempt to use the Finance Bill to force a vote on scrapping VAT on domestic fuel.

With the Democratic Unionist Party likely to oppose the Government on such a vote, it left her facing a possible embarrassing defeat, the Opposition claimed.

An amendment was expected because – like the notorious £350m-a-week extra for the NHS – zero-rating of fuel was a key plank of the Vote Leave campaign that secured Brexit.

Another likely challenge was over the issue of "period poverty", with ministers under pressure to agree to put in free sanitary products in schools.

The controversy comes hard-on-the-heels of the row over the Conservatives seizing control of all Commons committees – despite losing their majority at the general election.

The Independent revealed that plan ahead of it being forced through in September, potentially helping ministers to ram through up to 1,000 "corrections" to EU law ahead of Brexit.

Now Labour has accused the Government of a similar manoeuvre to prevent most amendments to the Finance Bill, which will enact last week's Budget.

"Once again we have further evidence of the Government's unprecedented rigging of Parliament because they cannot rely on their backbenchers or the DUP," said Peter Dowd, the Shadow Treasury Chief Secretary.

"This comes in the wake of the Tories stitch up of standing committees and its undemocratic and arrogant decision to ignore opposition motions."

And Paula Sherriff, the Labour MP who successfully amended the Budget over the so-called "tampon tax", told The Independent: "That ended up being welcomed on all sides of the House.

"And, this year, there are MPs across parties who want to press for action on period poverty and get a clear timetable for the tampon tax to come to an end with commitments to continue support for women's services.

"We can't let the Government shut down the debate. If they think this is over, they should think again."

However, the Government dismissed the controversy, describing the change to procedures for amendments as "a practical modernisation".

Increasingly, MPs have seized on the Finance Bill as a mechanism to force the Government to change course on tax measures – including over the "tampon tax" and over solar panels. In March last year, George Osborne was forced to announce the abolition of the 5 per cent VAT charged on women's sanitary products, after a cross-party revolt.

Labour campaigners joined forces with Eurosceptic Tories keen to assert Britain's power to set its own tax rates, forcing the then-Chancellor into the climbdown.

A similar alliance also forced Mr Osborne to scrap a proposed VAT hike on solar panels, wind turbines, hydropower equipment and energy efficiency products, from 5 per cent to 20 per cent.
