Nisa-Today's has completed an eight-month search for its first independent directors as part of its drive to deliver improved corporate governance for members.

The buying group has appointed Ian Black and Mark Pullen to the holdings board and the pair will report to non-executive chairman Raj Chatha.

They will be tasked with promoting strong trading initiatives and appropriate levels of corporate governance, as well as building better relationships between the board and Nisa members, employees, suppliers and the industry.

Chatha said the appointments of two objective board members would "allow us to realise and further develop our business strategy in 2008 and beyond, continuing our growth and securing the future of the group in the independent sector".

Black is an accountant and management consultant who has worked for PriceWaterhouseCoopers and KPMG, while Pullen was most recently group finance director for Geest.

Former chairman Edwin Booth first announced that Nisa was looking to appoint two independent board members in March. The group's corporate governance was widely criticised last year during the divisive collapse merger talks with Costcutter.
