DIARY: Sumo Cilla snowballs the opposition at AMV

Here's proof, if proof were needed, that Cilla "I don't know how she does it" Snowball really is possessed with extraordinary power.

The mother of three, housewife superstar, fills her spare time being the chief executive of Abbott Mead Vickers BBDO, the UK's biggest agency. Is there nothing that can make Snowball melt?

Apparently not. Although our picture won't do much for the lady's reputation for having a gentle and caring approach to management. Clearly, she actually enjoys beating the shit out of her staff.

The place: Regent's Park College in London. The occasion: AMV's summer party. This year's annual bonding had a Club 18-30 theme. No "Beaver Espana", though. AMV, after all, is meant to reflect David Abbott's dignity.

So instead of scenes resembling Faliraki at sunrise, everyone gathered round for some good old healthy party games. Hence Snowball's donning of a sumo wrestler's outfit for an It's A Knockout-style confrontation with Chloe Laughton, a AMV graduate trainee.

The result: a win for Snowball. Laughton has a reputation for feistiness but realised getting one over on your boss in front of the agency isn't a smart career move.
