Robert Breare, the founder and former chief executive of troubled portable hotel operator Snoozebox, has died.
The 60-year-old is understood to have passed away last week.
The news was met with sadness by Breare's former colleagues, including chef Justin Brown, who worked with Breare during his time as chairman of pub firm Merchant Inns.
"Very sad news to wake up this morning and hear that Robert Breare has passed away. Worked with him for 8 years at Merchant Inns," said Brown on social network Twitter.
Breare left Merchant Inns in 2009 and went on to found Snoozebox, a specialist in providing temporary hotel accommodation for major events such as the Edinburgh festivals an Silverstone Grand Prix.
He resigned from that business in May this year after it made a £4.4m loss in 2012, having failed to capitalise on its London Olympic Games village contract.
No details of how Breare died have yet emerged.
