In many ways the current Government has been highly successful. It has begun the long process of restoring sound money, made major reforms to a number of public services and managed to begin restructuring the bloated Welfare Bill.

Unfortunately, this is not reflected in the opinion polls.

Between them, the (small ‘c’) conservative parties have nearly 50 per cent, while the two major forces of the Left are on 42.5 per cent.

About two-thirds of Ukip supporters are former Conservatives. Thus the split in the Tory family – demonstrated by Douglas Carswell’s defection last month – makes it difficult for the Coalition to win an Election, potentially paving the way for Ed Miliband to win despite having little more than one-third of the vote.

The obvious answer is for the Tories and Ukip to do a pre-Election deal.

In a first-past-the-post system there is no prospect of doing a post-Election pact; each party takes too many of its voters from the same pool so there would not be enough combined MPs to form a coalition.

Now there are obstacles in the way of a pre-Election pact, but these are more emotional than rational.

It is said that the two leaders do not like each other, but Coalition has shown that Ministers from separate parties can work effectively with each other, and there is no obvious personal animosity between David Cameron and Nick Clegg or George Osborne and Danny Alexander. It is in the nature of politics that leaders attack each other, but that ought not unduly to upset a thick-skinned statesman.

Despite being held back by Coalition, the Prime Minister has still delivered some important Eurosceptic gains.

He vetoed the fiscal compact, voted against Mr Juncker, managed to cut the EU budget and enshrined in law a referendum lock on future treaties. Against this he is idiosyncratically supporting the European Arrest Warrant, which is a notable aspect of the creation of a federal Europe.

Nonetheless, this leaves the balance in his favour even if he seems sometimes to have responded to pressure.

What is certain is that his promise of an in/out referendum if returned in 2015 is sincere and can only happen if he wins.

This means that Ukip can achieve its main policy objective only if the Tories win the Election – yet it is the principal obstacle to this happening.

Sheer bloody mindedness is stopping the conservative family from dominating the UK political scene to achieve what all of us want. Regrettably, the Clacton by-election will make it worse, as positions become more entrenched. Therefore, some people have started suggesting that nothing can be done until after an Election at which point there will be some re-alignment of the Right.

This seems a defeatist view.

David Cameron has the opportunity to solve the problem now if he is generous.

The undoubted talents and charisma of Nigel Farage should be recognised.

He appeals to not only traditional Conservative members but also to those who have felt disenfranchised, people who feel that politicians are part of a too-cosy establishment while Ukip is shaking it up.

In some respects he appeals in a way that Boris Johnson does to those with Conservative values who are not necessarily Tory.

Prior to the Election such an offer needs to help Ukip in its ambition to win parliamentary seats. This could start with the House of Lords where, in spite of its recent electoral success, no new Ukip peer has been created.

It needs to be followed by deals in individual seats. There are a number vacant because of retirement, which may be suitable, as well as the ones where the Conservatives cannot expect to win and where Ukip is making inroads against Labour.

After the Election, if this strategy were adopted, there would be four Cabinet posts available through the removal of the Liberal Democrats.

Nigel Farage would be a much preferable Deputy Prime Minister to any true Conservative than Nick Clegg, while replacing Vince Cable with someone from Ukip would have a pleasant irony.

Perhaps as a sign of good faith even the Minister for Europe could be a Ukip MP.

If the Prime Minister were to do this he would suddenly have taken charge of events, no longer could his critics say – as Sir Walter Raleigh said of Elizabeth I – that he ‘did it all by halves’.

He would have gone further than he needed to go, rather than leaving the impression of being pushed unwillingly into something, and it would provide the launch pad for a General Election.

In the current atmosphere where politicians are so distrusted, it would act as a guarantee of how a future Conservative Government would be run because it would be beholden to a second party.

The promise of a referendum would clearly be of an unbreakable nature in coalition with Ukip, while the tone of the EU renegotiation would be considerably stronger.

It would have to be taken more seriously within the EU if a party that wanted to leave were in the Government. It would also be a recognition that all political parties are coalitions covering a range of views.

Historically, one of the strengths of the Tory Party has been its ability to stretch from Rab Butler to Enoch Powell in so civilized a way that Powell supported Butler’s leadership ambitions.

Narrowing the base with a third of potential supporters in another similar party is a sure way to defeat.

Generosity, courage and sense pave the path to victory.

Sadly, I doubt this will be done in time, so I am looking forward to some fair weather in Clacton for a spot of canvassing against a respected erstwhile colleague.
