The admission came at a debate featuring the chief executives of Business Post Group, TNT Mail UK and DHL Global Mail at last month's UK Mail Show Conference, and just under two months ahead of full deregulation of the UK postal services market.
Sarah Chambers, chairman of postal regulator Postcomm, said that despite limited deregulation so far, Royal Mail still retained 97.2 per cent of the market. TNT Mail UK chief executive Nick Wells said he thought Royal Mail would be "the dominant player and that's a good thing. But if we can take a 10-15 per cent share, we'd be happy with that."
However, Adam Crozier, chief executive of Royal Mail, said that Royal Mail is faced with falling mail volumes. Though it has managed a 20.5 per cent increase in operating profit to £159m in the six months to the end of September, profits in its letters business have declined.
The regulator also fended off criticism for the lack of progress on deregulation and its setting of the wholesale access price of 13p. Chambers said that Postcomm was "trying our damndest to get effective competition", while "ensuring that Royal Mail continue its universal service".
