Ashurst and Blackstone Chambers have represented Winterflood Securities on the trading company’s bid to overturn a 2008 market abuse ruling by the Financial Services Authority (FSA).

Ashurst litigation partner Edward Sparrow (pictured) instructed Blackstone Chambers’ Charles Flint QC on the appeal against the ruling, which saw Winterflood fined £4m for an “illegal share-ramping scheme” carried out in 2003-04.
