Rob McGregor, who left for 鈥榩ersonal reasons鈥, has been replaced by former chief operating officer

Rob McGregor has made a sudden exit from his role as chief executive of Apollo Group, three months after completing a refinancing deal with Lloyds Banking Group.

In an email to staff at the social housing firm he cited 鈥減ersonal reasons鈥 and said he would take a 鈥渕uch needed rest鈥 before deciding on his next move.

He has been replaced by Dave Sheridan (pictured), former chief operating officer, whose role will be left vacant.

McGregor鈥檚 email said: 鈥淭he group is in excellent shape, with a strong order book, strong finances and a high calibre management team, so I leave with the feeling of a job well done.鈥

He will surrender 16% of his 24% stake in the firm to the remaining management team, but will retain about 8% of the company.

Lloyds, which completed a refinancing deal in June to prepare for the sale of Apollo, has a stake of about 20%. This is included in a portfolio of 50 assets, which includes an interest in social housing group Keepmoat.

Sheridan said: 鈥淚 think Rob鈥檚 decision was as much of a surprise to Lloyds as it was to me. I don鈥檛 think he was getting a buzz from running the business anymore and wanted a new challenge. Rob鈥檚 a deep thinker; he鈥檚 talking about writing a book.鈥

Sheridan denied that the fallout from the Office of Fair Trading鈥檚 investigation into bid-rigging had played a part in McGregor鈥檚 departure. Last week Apollo was fined 拢2.2m for anti-competitive activity; this was 11.8% of its last stated pre-tax profit.

Asked about the progress of the Lloyds sale, Sheridan said: 鈥淯BS is still doing its review of the portfolio, but there is no news at the moment. It doesn鈥檛 impinge on us at all and it is business as usual.鈥

He said he would continue the company鈥檚 push into new areas of the UK and said the north-west of England was the next target area.
