A husband and wife team of estate agents with criminal convictions for insider dealing appear to have won another round in their battle to stay in business.

It is understood that regulator the National Trading Standards Estate Agency Team, at Powys County Council, has now said it will not be appealing against an earlier court decision.

This gave Christian and Angie Littlewood the right to have a hearing in person with an adjudicator. The couple had appealed following the regulator’s decision to ban them from the industry.

The High Court judge described Powys’s system as “unlawful” in the way it dealt with appeals – by looking at evidence, rather than at live hearings.

The case also highlighted concerns over Powys’s case load.

The Littlewoods were found guilty of insider trading in 2010.

Christian Littlewood, who earned £1.5m a year as an investment banker with Dresdner Kleinwort, and his wife Angie, had used cash from their illegal trades to buy a string of properties.

Littlewood was jailed for three years and four months while his wife was given a one-year suspended sentence.

They have since set up as estate agents, but Powys attempted to ban them from the industry on the grounds that they were not fit and proper people.

According to a report in the local Welsh press, the costs in the case to Powys will be between £90,000 and £100,000.

While the Littlewoods run a business classified as an estate agency, it is understood that this does not deal in lettings and that the Littlewoods are emphasising that it does not handle money. The business is signed up to a redress scheme, as is legally required.
