Hilton Group has confirmed that Peter George will stand down as chief executive from the end of this month.
He will remain vice chairman and a director until 31 August, when he will retire from the company.
David Michels, currently chief executive of Hilton International hotels, will take over as group chief executive on 1 June.
Further movers include Anthony Harris, currently chief operating officer, who will become chief executive officer of Hilton International and join the Hilton Group board.
Hilton also announced today that trading during the first four months of its current financial year was "broadly in line with our expectations".
Revenue per available room (revpar) increased worldwide by 6.3% when compared with the first four months of the previous year. In the UK, revpar was 8% ahead of last year, with London up 5.7% and provincial hotels by 8.8%.
In Continental Europe, several cities including Paris, Barcelona and Rome showed very strong growth and revpar across the area was by 10.5% in constant currencies, but only 3.6% after taking into account the weakness of the euro.
The Americas benefited from a strong performance by Hilton's Canadian hotels, but business in the Asia Pacific region "remained difficult".
During the period, Hilton signed 11 new management contracts and 20 new hotels will open next year. The extension to the Hilton London Metropole hotel is set to open on 1 October.
