Sometimes it is the little things that signal the kind of big change Britain will undergo if we get a Tory government.

When I say little, I mean not the driving issues of the economy and the future of schools and hospitals (safer under Labour on all counts) but the sometimes symbolic changes that indicate something deeper.

Like the news, which probably won’t make the national media radar, that the Tories are backing the efforts of tobacco companies to overturn the ban on display of tobacco products.

If we are talking health grounds, the argument against is overwhelming. If we are talking economic groiunds, the case for change is minimal.

But what it signals is that when it comes to standing up to vested interests, Cameron and Co won’t have what it takes, particularly if those vested interests are on the money side of the fence.

Oh, and there is the small matter of Ken Clarke’s large salary enjoyed down the years courtesy of one of the world’s leading tobacco giants.

If the Tories were serious about fighting cancer the last thing they would be doing is bowing down before the tobacco lobby, particularly after the hard won changes on this front made under Labour. (And before anyone shouts Ecclestone, let me remind you the tobacco advertising ban was implemented, and a large donation repaid).

But then whey should anyone think the Tories are serious about this issue when one of the first things they will do if elected is to scrap the cancer guarantee under Labour that cancer patients will see a specialist within a fortnight of being diagnosed.

It will not be the only change,  nor the only piece of Labour progress to be undone, but I thought it worth drawing to your attention.

Don’t expect to see Mr Clarke chased around on it, or the marginalised Mr Lansley (he who would be health secretary in a Cameron government now you ask)
