This is Theresa May's worst day of the campaign

Tuesday marked the first interesting thing to happen on the Conservative campaign.

In news which delighted journalists and the other eleven people following political Twitter, Theresa May appeared to break from her controlled mantra and actually announce something at a press conference.

Or in this instance, un-announce something she'd announced four days earlier.

On Thursday, the Conservatives launched their 2017 manifesto. It contained a promise to change the way social care provision was funded.

The Tories proposed making the elderly pay for their social care, changing the threshold for means testing from £23,250 to £100,000.

However, for this threshold would no include the value of a person's property.

In the event a person needed long term care, for instance if they were to suffer dementia, the cost of that would be paid for by them down to their last £100,000 in their pockets.

May then used today's Welsh Conservatives event to announce there would be an upper limit on how much a person would contribute to their own social care costs.

She denied it was u-turn.

Tightening Polls

Before the u-turn, the morning wasn't off to a great start.

Yet another opinion poll was published, showing the gap narrowing between the Tories and the Labour opposition.

On Monday, a poll by Survation put Labour on 34 per cent to a Tory 43 per cent.

On the same day the ICM poll showed a less dramatic change: Labour 33 per cent, and the Conservatives on 47 per cent.

Previously a poll by YouGov carried out on the day of the Tory manifesto launch put their lead at just 9 per cent.

So not the best start to May's day.

Then the apparent u-turn came.

In the face of the press May became visibly irritable, denying there had been a change to the manifesto.

Shaking her head as the BBC’s Laura Keunssberg asked about the manifesto changes, May also insisted the cap was nothing new.

Social media then made her day worse, quickly

There were also some good points about the stability she'd brought. To the Labour Party.

Return of the Osbo

The Chancellor she sacked, and then effectively bounced out of holding onto his seat in the Commons made his first formal counter-strike on Monday morning.

In this instance the choice iof the messenger was as much a hammer blow to May’s credibility as the message.

George Osborne, now the editor of the London Evening Standard, used a front page, and tweeted it, to announce May’s coming u-turn.

The once and future king of the Cameronite wing of the Conservative Party is clearly still plugged in to Westminster.

While he spends the day at Stamford Bridge with the likes of John Terry, modern technology means he can Twitter bomb his undoer from a safe distance.

Oh to be a former Chancellor.

This is Theresa May's worst day of the campaign

Which isn't saying much.

Her tightly controlled campaign has finally been given enough wiggle room that it might wobble.

Despite this, May remains high in the opinion polls above Corbyn.

Even with a tightened gap, she's still being predicted a stable Conservative majority, untrammelled by the straightjacket David Cameron was forced into by parliamentary arithmetic.

And the notion that it might be a close election could also motivate lazy Tories to get out and vote on 8 June.

So put the champagne socialism away.

It's not nearly over yet.
