Another cheeky publicity stunt from a financial betting company determined to shock the City into parting with some increasingly scarce cash.

BetOnMarkets.com streaked through the Square Mile yesterday with naked men handing out scratch cards offering punters free trades to mark the launch of its 30 second flash betting initiative.

OK, so those genitals you see on show above are actually attached to a "naked suit" - but they must have put a smile on the faces of jaded City ladies, at the very least.
