Nisa-Today's bosses said the roles were designed to bring outside experience, knowledge and perspective to the board. Members have for some time called for improved corporate governance from the board.
In a separate process, the group is to hold elections to vote members to the board.
The new positions will be filled by Ian Black, former accountant and management consultant with PriceWaterHouseCoopers and KPMG, and Mark Pullen, who has worked in the consumer goods industry for more than 30 years, recently as group finance director for ready meals provider Geest Plc. The appointments will take effect from January 1, 2008.
Prominent Nisa member Mark Proudfoot welcomed the appointments and told Convenience Store: "This is an excellent move, although it should have happened some time ago. They are very good candidates and I hope they will both bring refreshing views to the business. It is, however, disappointing that they will not be in their positions in time for the AGM on November 28, the roadshows and regional meetings.
"I would add that none of this would have happened if it had not been for members working together last year to bring about change."
The new directors will report to non-executive chairman Raj Chatha. He said: "Ian and Mark's appointments bring extensive experience to the Holdings Board. This, combined with an objective view of our operations, will allow us to develop our business strategy in 2008 and beyond."
