Tories or Labour, who deserves the credit for success?

The key marginal seat of Cannock Chase was one that got briefly flagged up on the Conservative website as 'non-target'.

Labour might have weaponised the NHS, but the Tories have weaponised Boris Johnson.

The blonde bombshell exploded in the Premier Suite in a sea of selfies, speeches and pancake tossing.

Hot on the heels of visits from the Chancellor, it's obvious that the party wants to hold the constituency where it was gifted its biggest swing from Labour in 2010.

Of course Labour were no slouches this week when it came to visiting marginal seats.

Wolverhampton North East, where shadow housing minister Emma Reynolds is MP, has a smaller Labour majority than the Tory one in Cannock.

But it should, in theory, be easier to hold on to. After all, if the Tories could not take it from Labour in 2010 when they were the fresh faces of opposition, the task is doubly difficult after five years in power.

So having not one but four shadow cabinet ministers decamp to Wolverhampton and the Jaguar Land Rover engine plant would have done a lot for Miss Reynolds. She spoke during the party's launch of its economic plan on the factory floor of how the time JLR announced it was coming to the city was her proudest day as an MP.

That was a bit rich for South Staffordshire Conservative MP Gavin Williamson.

After all, the factory is actually in his constituency.

That's not the only territorial issue either. The Conservatives want everyone to know it was under the Coalition that JLR came to the i54 and transformed what was predominantly an empty field into one of the biggest single pieces of private sector investment in Wolverhampton/South Staffordshire for a generation. In particular, he says the site never even had electricity and gas in all the years under Labour that it was lying vacant.

Miss Reynolds, however, reminds everyone it was the work of Advantage West Midlands, the old regional development agency, that turned a polluted patch of land by the motorway into prime development space.

AWM was scrapped by the Coalition. And while Labour isn't happy about that, it won't be bringing it back if it wins the election.

There is however, another group that deserves a lot more credit than any politicians. And that's Jaguar Land Rover itself for having survived the recession and come out of it stronger than ever and willing to actually invest here at all. Without that, the i54 would still be an empty field whoever was in power.

I am the Ed man, They are the Ed men (And woman), I am the walrus

The Conservative party's press office seized on our photograph of Labour's front benchers at Jaguar Land Rover this week.

Ed Miliband, Caroline Flint, Ed Balls and Chuka Umunna walked along a zebra crossing on the factory floor in a scene reminiscent of The Beatles' Abbey Road album cover, except with hi-vis vests and facing left (which is appropriate when you think about it).

Rather than seeing their opponents as something of a Fab Four, Conservative HQ decided another Beatles related title was more suitable - Back In The USSR.

Another suggested song title was a bit of a dig at Ed Balls and his suggestion of a way to ensure small traders pay all their tax - All You Need Is Love (And A Receipt).
