The Steam Packet has issued an apology to Shoprite over comments made by the ferry company's chief executive, Mark Woodward.
In statement, Mr Woodward describes the supermarket chain as 'a valuable and committed customer of the Steam Packet Company'.
And he apologises for any misleading impression given that Shoprite was not committed to supporting the Island's economy.
The apology follows a comment in the local press in which Mr Woodward quoted Shoprite's motto and questioned whether the firm was really 'Manx to the Max', which the supermarket chain objected to strongly.
Shoprite says it is doing business with both the Packet and its freight competitor Mezeron, using seven different hauliers to bring goods to the Island.
The statement concludes by saying the Steam Packet recognises 'the significant contribution Shoprite makes to the Island's economy', by employing around 600 Manx workers and supporting Manx domiciled businesses.
