The Financial Services Authority (FSA) has secured a high-profile prosecution against a former Dresdner investment banker for insider dealing, in the latest crackdown on market abuse by the City regulator.

Christian Littlewood has been sentenced to three years and four months in prison for eight counts of insider trading which occurred between 2000 and 2008 during his employment at Dresdner and most recently Shore Capital. During this time he accrued a total of £590,000 in relation to the charged offences.
