Diary: Why Sorrell was left with a frosty opinion of Davos

Diary would like to offer you its favourite snap from the Davos World Economic Forum. We just love the cuddly creature with the cold nose and the hangdog expression. But enough about Sir Martin Sorrell. The dog looks pretty cute too.

WPP's chief executive (clearly pleased about the new man in the Oval Office) and his FT-reading canine companion are pictured taking the Alpine air during a break in proceedings.

For those ad-watchers with a good memory, the picture will be reminiscent of DDB's FT campaign that ran before Christmas. Sorrell endorsing an ad from Omnicom. Who would have thought?

Davos itself saw more adlanders rubbing shoulders with the great and good. Not least David Jones, the Euro RSCG chief, who shared a stage with the former United Nations secretary general, Kofi Annan.

Sorrell, meanwhile,has had some icy comments to make about the Forum in his FT blog. The event has become far too crowded, he complained. Some people couldn't get into the sessions and tight security just aggravated the crush.

To make matters worse, Sorrell participated in a CNBC session where he claimed there "didn't seem to be too much understanding" of the issues involved.

No doubt all of this has gone down like a lead balloon with Sorrell's wife, Cristina Falcone, who happens to be a WEF director.
