If a recent High Court writ is anything to go by then the trials and tribulations of being the FSA boss will seem like child’s play.

Hector Sants, the new chief executive, is reportedly preparing to go head-to-head with a City financier in a bitter row over the lapsed sale of his former country home.

The pair are due for a High Court show-down to settle the £750,000 spat after the financier allegedly pulled out of the £3.6m sale.

And who said it was just broker commission, TCF, contract certainty and MiFID that caused industry headaches?
