Rural & General Insurance founder Charles Pratten was last week granted a court date for his retrial on offences relating to obtaining a financial advantage by deception.

Mr Pratten will return to the NSW Supreme Court on May 18 next year for a trial expected to take some weeks.

He was convicted of the offences in June 2012 on seven charges, which relate to tax returns between 2003 and 2009.

He appealed the decision and three appeal judges earlier this year ordered a retrial.
