I doubt many real Conservatives will back Cameron. He had to be dragged kicking and screaming to support Conservative policies and has in recent speeches shown support for his old pink and green policies. The Conservative Party will have to get rid of him.

Peter, London,

What is the matter with people - Labour's tenure in office has been one of incompetence and betrayal! Brown has no solutions for the major problems facing this country, including immigration which is a problem of his Government's making.

Edwin T: 0% of the electorate backed Macmillan between 1957 and 1959, Douglas Home 1963-4,Callaghan 1976-9 and Major 1990-92. If you want to change the constitution then say so (perhaps we could start with electoral reform) but don't pretend, as so many people are doing now, that something new has happened since Blair resigned..

I have no doubt the no-vote-party would again come top of the polls.

@Edwin T: "0% of the electorate have so far backed Brown" - not quite true in that a few people in his own constituency have explicitly backed him, but granted not as PM. But then, nobody has backed any of the other party leaders as PM either as neither Cameron nor Campbell notr whoever replaces him were in post at the last general election. Which leads us back to that old saw that we have a parliamentary democracy and we don't directly elect PMs.

Post-1945 electoral history suggests that the four consecutive wins for the Tories under Thatcher and Major were an aberration for which the Conservatives paid a heavy price by suffering their worst-ever defeat in 1997. Three consecutive wins for any party should be as much as they can expect in a democracy largely based on the two-party system. Consequently, Gordon Brown will most likely turn out to be to Tony Blair what James Callaghan was to Harold Wilson, the inheritor of a government which lost the subsequent election. But that all depends on "events, dear boy, events," so David Cameron shouldn't necessarily expect to be posing in front of Number 10 in a year or so's time, not by any manner of means.

Personally, I think the electorate consider both Labour and Conservative parties as a choice between two evils. Neither reflects public opinion or aspirations and both seem equally incompetent at ever achieving it. My vote will go elsewhere.

I very much doubt that any change in the polls for the Lib Dems is a result of their leadership contest. This has received very little press (although it has achieved some, and therefore is an improvement in Lib Dem terms). More likely is simply the normal pattern of politics: the Lib Dems are the party to whom people turn when they do not like either of the other two, only ever an alternative, never the first choice. Improved Lib Dem poll ratings on that analysis are therefore an indictment of the other parties.

John Scott, Cambridge,

Yes, but 0% of the electorate have so far backed Brown. And we all await the opportunity with bated hostility.
