THE political earthquake – so long predicted but which so few believed – is now happening. The results in the council elections and for the European parliament are a triumph for Ukip and a catastrophe for the three main British parties.

The campaign for next year’s General Election has started this week. I will repeat my earlier prophecy that 2014/15 will see the most momentous changes in our national politics – certainly bigger than anything that has happened since 1945. Politics is suddenly interesting again. And what makes it so interesting is that no one knows which party, if any, will win the General Election.

What do we know? We know that the Lib Dems will be wiped out and the Tories will receive a short, sharp shock. On second thoughts, make that a long, sharp shock.

But what will happen to Labour? That’s the riddle wrapped in a mystery inside an enigma.

One thing is clear: Ed Miliband has suffered a terrible personal defeat, amounting to a vote of no confidence from his own party. The question is whether they will be tempted – forced? – to change their leader.

If t’were done when ‘tis done, then t’were best t’were done quickly. Miliband may be a turkey, but the party apparatchiks dare not leave his execution until Christmas.

So what of the Tories in general and Dave Cameron in particular? Even after the cataclysmic, for him, election results of last weekend and despite his protestations, Mr Cameron still doesn’t “get it”.

Throughout the country people have shown they are sick of him and his party.

How do I know Dave still doesn’t get it?

Because he has sent me – and everyone in the country, I suppose – a propaganda letter following the recent elections. This is what he says: “Now we must continue our focus on the big issues facing Britain. We need to carry on reducing the deficit to safeguard our economy for the long term.”

Fact: but the country will be borrowing more next year than it did when the slump started five or six years ago.

“We need to keep on backing businesses so they can create even more jobs and give even more people the security of a pay packet each month.”

Fact: his promised “bonfire of the quangos” has never happened .

But Mr Cameron has saved his most ribtickling joke to the last. He says: “We need to continue to control immigration and fix the welfare system so our economy delivers for those who want to work hard and play by the rules.”

It’s that word “continue” which really makes me fall about. “We need to continue to control immigration…” They haven’t started. They don’t even know how many foreigners are coming in each year.

And, disgracefully, we are not allowed to express concern about immigration without being denounced as “racist”.

But there is nothing racist about being interested in the character of our own country. He says he wants to make sure the economy “delivers for those who want to work hard”. What, with nearly a million under 25-year-olds on the dole – the lost generation?

Of course, it’s the Tories’ shameful unwillingness to cut those business taxes and regulations which keeps these youngsters jobless.

There will be trouble ahead…for Dave.
