CSC's UK managing director David Rasche suddenly quit the company this week as the software giant gears up for a major restructuring programme within its UK operations.

Rasche will leave the company tomorrow (November 10). Ex-acquisitions boss Andrew Spray will now become the group's UK managing director.

Rasche headed CSC's financial services arm from April 1999 to April this year during which time he headed the group's banking, insurer, and retail divisions.

At the end of the last financial year he returned to head the retail division where he also drafted European strategy for the group.

CSC marketing director Tony Barker would only say of Rasche's shock departure that he had quit to “pursue other interests”.

But an insider at the company said Rasche was unhappy at both the direction CSC was taking and also the possibility of spending more time working away from his family in London.

“I think it's fair to say that David was happy being a big fish in a small pond, but he liked the idea of being a small fish in a bigger pond less,” the insider said.

Under the restructuring programme, CSC is planning to combine its retail and general insurance divisions. Barker said the rationalisation programmme would create some synergy, but claimed the company had yet to work out what the implications would be on staffing levels.
