A group of London marine insurance market heavyweights have been piling on the pounds sterling while slipping off the pounds avoirdupois.

They aimed to raise £10,000 ($14,200) for a Parkinson’s disease charity through a sponsored slim and have beaten their target by 13%, with a total of £11,385 so far.

However, they are not disclosing how much of their combined weight of 2,471 pounds has disappeared.
