In our news story concerning NHS planning director Alasdair Liddell's departure from the Department of Health (pages 4-5, 11 May), we misquoted NHS finance director Colin Reeves, whose wholehearted tribute to Mr Liddell included praise for his role in 'setting the strategic agenda for the NHS Executive'.The company Mr Liddell is joining as director of government services is iMPOWER, and not iMPACT, as we reported.

We apologise for the error.
