When the Tories came to power in 2015, it was under posh chillaxing Remain-backer David Cameron .

Two years later they are steering the Brexit ship under the frosty glare of Theresa May - so expect an awful lot to change.

Many of the Conservatives' pledges were made until "the end of this Parliament", which everyone thought would be in 2020.

Now, however, the Parliament will end at one minute past midnight on Wednesday 3 May.

If she wins the snap election on June 8, it gives Theresa May sweeping freedom to tear up previous promises that weighed her down.

Of course, the Tory manifesto for the 2017 election - not yet published - will include a long list of promises of its own.

But today Mrs May signalled she will abandon some pledges that were made in 2015.

She told ITV News: "I stood on the Conservative Party manifesto in 2015, but that manifesto was for a time when there was going to be a referendum but there was a general assumption that we would stay in the EU.

"Things have changed. We are leaving the European Union. We need to look now for a different future."

Here are some of the biggest promises she is free to scrap in that "different future", if she wants to.

1. Protecting people's pensions

A key promise to older voters in 2015 was that their pensions would keep rising.

That's thanks to the "triple lock", which promises state pensions go up every year with either inflation, average earnings or 2.5% - whichever is highest.

Labour committed to keep the triple lock up to 2025, but experts have been calling on the Tories to scrap it because it is so expensive.

Ministers have clearly promised only to protect the triple lock "for the whole of this parliament".

Former pensions minister Steve Webb said: "The triple lock on the state pension must now be up for grabs."

2. Banning new welfare cuts

The Tories had ruled out any new benefit cuts - but only in this Parliament.

Chancellor Philip Hammond said in February: "We have no plans for further welfare reforms in this Parliament."

Work and Pensions Secretary Damian Green added: "We are not going to have any new welfare cuts in this Parliament, apart from those that have already been legislated for."

New benefit cuts would spark huge protests, and Theresa May's administration has said it won't cut benefits further.

But a new manifesto, and the temptation of a bigger majority, would free up the Tories to attack welfare without breaking their pledge.

3. Banning National Insurance hikes

Chancellor Philip Hammond was forced to ditch a 2% National Insurance hike for the self-employed because it broke the 2015 manifesto.

His party had promised there would be no rises in "VAT, National Insurance contributions or Income Tax".

He scrapped the changes in a humiliating turnaround just a few days after last month's Budget.

But his promise said only: "There will be no increases to NICs rates in this Parliament."

That leaves him free to raise NICs this autumn, which would be embarrassing, but if there's a huge Tory majority it may get through.

4. Capping commuters' rail fares

Ministers pledged not to let regulated rail fares rise any higher than the RPI rate of inflation... "for the life of this Parliament".

That means the promise made repeatedly by ministers is set to expire at the beginning of May, not in 2020 as planned.

Any new pledge will be for the party to make in its manifesto, of course.

5. Protecting freebies for pensioners

The 2015 manifesto promised pensioners they wouldn't lose any of their other benefits.

These included the Winter Fuel Payments, free bus passes, free prescriptions and TV licences - "for the next Parliament".

Ministers would now be free to rescind this or tweak it without breaking their promise.

6. 'Protecting' school budgets

The 2015 manifesto boldly claimed "there will be a real-terms increase in the schools budget in the next Parliament".

Unions and experts say this promise has already become null and void under Theresa May.

A new formula will cut 5,500 schools' funding by 3%, and the respected IFS think tank said real-terms funding (once inflation is counted) is already set to be cut overall.

The IFS said: “This will be the first time schools have seen real-terms cuts in spending per pupil since the mid-1990s.”

Will the Conservatives drop this rather awkward wording from their next manifesto to make sure their cuts go ahead?

Or will they drop the funding formula instead?

7. Helping people pay less tax

The Tories have slowly been raising threshold at which low earners start paying income tax - currently £11,500.

They had promised to raise the personal allowance, as it's called, to £12,500 "by the end of this Parliament".

Clearly that will no longer happen. So will the personal allowance still hit £12,500 in 2020, when the parliament was supposed to end?

And what about the 40p rate threshold, which was meant to hit £50,000 by the end of the parliament too?

The Tories' prediction of a £9 minimum wage for over-25s has already been downgraded to £8.75 due to worse-than-expected finances.

Now they'd be perfectly free to tweak their planned rises without breaking any promises.
