Most reactions to Ken Clarke's return on last night's thread were positive. The same is true of reactions from bloggers and commentators. Arranged below are key arguments.
The economic times are so serious that David Cameron is correct to bring such a successful former Chancellor back to the frontbench: "The world has changed, and if in response to the resulting tumult Barack Obama can do a deal with Mrs Clinton and Gordon Brown can rediscover his friendship with Peter Mandelson, then surely the Tories should be able to bury the hatchet (in their opponents rather than each other) in order to turf out Labour?" - Iain Martin
His time as Chancellor remains respected (even to The Independent): "His tenure at the Treasury remains highly regarded – something that cannot be said of all former Chancellors."
Ken Clarke can make complex economic issues understandable: "He may also be the Tories' Vince Cable. What Cable does is talk about economics in clear English - not using Brown's jargons, nor the soundbites Osborne often uses. To Clarke, economics is easy - and, like Cable, he makes it sound easy. It has been a joy listening to him on the economy recently." - Fraser Nelson
Clarke's pro-European views may create tensions: "Mr Clarke's pro European views - in particular, his support for Britain scrapping the pound and joining the Euro - have alienated him from the mainstream of his party. The issue of Europe is still a live one since some now argue that the current economic crisis demonstrates the case for the Euro. Also, the Tories are opposed to the Lisbon EU Treaty which Clarke has backed and they are committed to holding a referendum on it which could lead to a Cameron-led government Britain re-negotiating Britain's relationship with the EU." - Nick Robinson
Ken's European views will be submerged within his acceptance of shadow cabinet responsibility: "To those Tories who recoil in horror at the return of Ken Clarke, I'd say this. Few of us agree with his views on Europe, but they should not be allowed to colour the fact that he is a big hitter and is very popular with people who are either soft Tories or not Tories at all. He will have to abide by the same collective responsibility as the Shadow Cabinet and will know that." - Iain Dale
The Conservatives have invited a very loose cannon into their highest ranks: "Mr Clarke has always said precisely what he thought on matters relating to the EU, having appeared on platforms with his political opponents to the detriment of the Conservative Party and to the embarrassment of the Leader. Indeed, he even favours a coalition with the europhile Liberal Democrats, and has publicly said so. He is a loose cannon, and regularly defies the Party whip with impunity: indeed, his voting record identifies him as a rebel." - Cranmer
Clarke's return is a boost to those who wish to see the Tories form a deal with the Liberal Democrats: "Let's not forget that Clarke sees coalition with the Lib Dems as a good thing. As he told me three years ago "I'm glad to say the fates could condemn the Conservatives and the Liberals to form a coalition." - Fraser Nelson
And finally... a Conservative MP emailed me this cartoon from 1993. No further comment necessary:
