David Cameron and George Osborne raise a glass in Wolverhampton

David Cameron and George Osborne arrived in Wolverhampton by helicopter, landing at Wergs Golf Club, before they were driven the last few miles to Banks's Brewery.

Their celebrity style of travel, complete with an entourage coming by coach, was befitting for a Prime Minister who had revealed himself to be a distant relation of Kim Kardashian.

And no, that was not an April Fool, despite the date.

They had much to raise a glass for with brewery giant Marston's.

After all chief executive Ralph Findlay was one of 103 business leaders who had signed a letter praising the Tories for the recovery and warning it was all at risk with Labour.

Also on the letter were Baroness (Karren Brady), the former Birmingham City managing director, and Lord (Anthony) Bamford, of Staffordshire's JCB.

These were perhaps unsurprising signatories, however, given they are both Conservative peers.

Lord Bamford is also well known as a Conservative donor.

The Prime Minister and the Chancellor had plenty of places they could have taken the magical mystery tour of hacks who rolled up on the coach.

But Wolverhampton South West was as good a place as any to do it.

After all, the Conservatives are defending a very slender 691 majority here that was won by Paul Uppal in 2010.

The Tories have to be able to show that their 'long term economic plan' is working.

So much so that Mr Cameron crowbarred that phrase into almost every answer he gave.

The duo were taken off for a meeting with Mr Findlay and a look around the Park brewery.

They chatted in the yard surrounded by kegs.

Sadly they did not get close enough to the ones filled with cider for if they had they might have smiled at the brand contained within – Thatcher's.

No hard hats on this tour, despite Marston's re-building a lot of the site at the moment. The Chancellor does like those. They are generally a sign that things are moving, that Britain is getting back to work.

Hard hats after hard decisions mean hard cash being spent providing hard jobs for hard working people.

But Mr Osborne was able to don a pair of safety gloves and hammer a stopper into a barrel while the Prime Minister looked on.

The pair are committed to each other for the next five years, although Mr Osborne left to head for Yorkshire while Mr Cameron did interviews with the waiting Press. Mr Osborne will stay on as Chancellor.

That's if they win, of course.

As Mr Cameron answered questions on his pledge to recruit more GPs he acknowledged he might not get to carry it out.

"There are more GPs in our country, 1,000 more since the election and we are recruiting more GPs," he said. "The Royal College of GPs said the other day that there had never been a better time to be a GP. I'm confident with the extra investment we are putting in and the high regard that we hold GPs in our country that we will fulfil our plans.

"We've piloted a new approach of seven day opening. The parts of the country where that's happened have seen the pressure come off A&E. We want that for everyone.

"I really hope to be in office to fulfil that."

But what of the enormous pressure on the NHS? Given that he and Mr Osborne have just ruled out increases in VAT, national insurance and income tax, how is he going to do it?

"We have full control of the nation's finances and we have ruled out increases in VAT, NICs and income tax. We will find savings in government waste," the Prime Minister said.

"We want to see childcare expanded. This is the first government to fund 15 hours for three and four year olds and we extended that to two year olds and we're bringing in tax relief on childcare.

"I said five years ago we would cut the deficit, not the NHS and that's what we have done. We've done that while increasing spending on the NHS.

"The health service is special to me. It has been there for my family and it is there for families in the West Midlands."

But Mr Cameron said he wanted to help smaller traders too. "There are two things we are doing right now that really help small businesses," he said. "One is the employment allowance, which saves small businesses up to £2,000 on their national insurance.

"We're just about to bring in a change which is if you employ a young person you pay no national insurance at all and I think that will help small businesses.

"We've also helped with business rates. But above all, small businesses benefit when you have a long term economic plan that's working. That's what we have with inflation at zero per cent, with living standards growing and jobs growing by 1,000 a day. We've got a successful growing economy and we mustn't put that at risk."

Most of the assembled Press thought the story that he was related to Kim Kardashian, the reality TV star with the impressive derriere, was just a joke.

It was not: "I found out about this because it appeared somewhere. A cousin of mine checked it out and it's apparently true. You have to go back about 13 generations to find the link between Kim Kardashian and myself. We're not planning a family reunion any time soon. I'm going to be a bit busy so I won't be keeping up with the Kardashians. I want to keep up the economic plan."

Labour plans to reverse the Tories cut in corporation tax and use the money to support 1.5 million small businesses.

The letter from the business leaders said: "We believe a change in course will threaten jobs and deter investment. This would send a negative message about Britain and put the recovery at risk." The letter did not give explicit backing for any party in the May 7 election, but said: "This Conservative-led Government has been good for business and has pursued policies which have supported investment and job creation."

That prompted George Osborne to seize on it. Mr Osborne said: "The warning from Britain's business leaders couldn't be clearer: A change of course will threaten jobs, deter investment, send a negative signal about our country and put the recovery at risk."

UKIP's economics spokesman Patrick O'Flynn said: "I am not surprised to see business leaders steer a wide path away from the Labour Party. However I also think that just rounding up 100 business names and saying that George Osborne's a jolly good chap might not be the boon that it might once have been for the Conservative Party, because there are profound questions about the way our economy works and about living standards for ordinary British working people and indeed about corporate tax dodging too."

Signatories, who included BP chief executive Bob Dudley, Prudential chief executive Tidjane Thiam and Dixons Carphone chairman Sir Charles Dunstone, stressed they were putting their names to the letter in a personal capacity.

The letter may not have done much to sway opinion for ordinary voters, unless the Conservatives can make the case that helping out big businesses means helping those who create jobs and therefore means helping people into jobs.
