Graham Mackay had surgery for a brain tumour in April

SABMiller has granted its chairman a "medical leave of absence" while he recovers from surgery for a brain tumour. 

Graham Mackay was diagnosed with the tumour in April and replaced immediately as the group's CEO by Alan Clark. The planned switch was due to happen next month

John Manser, the group's deputy chairman was installed as acting chairman following news of Mackay's illness. Manser will continue in the role "for the time being", SABMiller said today (6 June). 

"The board will keep the position under review as Mr Mackay's treatment progresses, and an appropriate announcement about the future will be made as soon as any definitive decisions have been taken," the company said in a filing to the London Stock Exchange. 

Manser has stood down as chairman of the group's audit committee today, a year earlier than originally planned, and retired from the audit and remuneration committees. Mark Armour has replaced Manser as audit committee chairman.
