Ken Clarke's remarks are an open goal to ambitious Lib Dems.

Lets presume for a minute that Ken Clarke is right to say that a hung parliament would be a potential economic disaster. Lets say he's right that the country needs a party with a clear majority running the country. Which party is now positioned to provide that strong majority? Labour can be ruled out. The conservatives following the Liberal Democrat poll surge are realistically not going to become the consensus choice for change. They weren't even high enough in the polls to achieve a majority before people realised this was a three-party race.

From this analysis of some YouGov polling http://www.today.yougov.co.uk/commentaries/peter-kellner/could-lib-dems-win-outright it seems quite clear that the Lib Dems can achieve a strong majority if the 49% of people who would vote for them if they thought they could win actually began to believe they could win. Only 21% of those polled would be dismayed at a Lib Dem majority. If either of the other parties are introduced into a potential outcome dismay in the outcome soars, with the least dismal being a labour-liberal coalition at 39% dismayed.

The only party that can achieve a strong majority government now is the Lib Dems. Ken Clarke says a majority is needed for us to avoid economic meltdown...

Also, how would the markets respond to George Osborne loose in the treasury relative to Vince Cable taking his seat at the money table? Vince has set out in some detail his plans for reducing the deficit and been honest about tough times ahead. George has plucked a £6bn tax cut out of thin air at the last minute in a desperate attempt to win votes.

I'm presuming of course that George is the Conservative choice to be chancellor, but given the rolling out of Ken to deliver the horrific IMF news, maybe there's been a change of plan...
