Commenting on his time as Chief Executive Brian said: "I really appreciate the superb support I receive from the staff, management, the Board and members. Knowing the depth of backing I have ensures that we are prepared for the toughest challenges, and there have been a number of them over the years in which I have been at the helm."

He added: "It is never easy to decide when to go and, whilst it would be possible to stay on for a while, I am already well past the timing I envisaged a few years ago. It is only right to announce a date some months ahead enabling time for a full search and proper handover to my successor.

"It would have been desirable to hand over in a more favourable trading environment but I suspect that is some years away. However, the financial strength and breadth of the Group leaves me optimistic for its future prospects."

John McIntosh, Chairman of ANM Group said that the board respected Mr Pack's decision and were pleased that they had an adequate lead in time to ensure an orderly handover.

He added: "Over the years, Brian has been a tower of strength and inspiration to all involved in the Group and he leaves us in a strong position to face the future, it is good to know his wise counsel will still be available to us due to his deep commitment to the well being of the Group."
