Alan Sugar has stepped down as chairman of Viglen, having steered the system builder for more than 32 years.
According to a filing at Companies House, Sugar, who was recently appointed as the government's enterprise tzar and has helmed BBC 1's The Apprentice since 2005, handed in his notice on 1 July - the same day he resigned from Amstrad.
The UK system builder market has more than halved in numbers during the past six years due to intense competition from tier-one PC suppliers. Viglen has not been immune, as its last set of results revealed.
The company was the subject of a takeover bid by Staffordshire-based Stone Computers, until the deal hit the rocks due to financial issues that neither party was able to overcome.
Sugar's departure heralds another round of talks between Viglen and potential buyers, according to sources close to the firm.
Claude Littner, who traditionally joins Sugar in the semi-final of The Apprentice each year to interview the last remaining candidates, became a director at Viglen on the same day that Sugar resigned.
He also holds directorships at Powerleague, Aspire Oil Services, Blacks Leisure Group and Myeloma UK.
Over three decades, Viglen has carved out a niche in the public sector and currently supplies local and central government as a supplier under the OGC Buying Solutions framework and education institutions through Becta.
Viglen was unavailable to comment at the time of going to press.
