The London region of the NHS has the highest number of GPs approaching retirement in England. It calculates that 206 of its 4,000 GPs - or roughly 5 per cent of the total - are aged 64 or over, although this means they have in theory up to six years before retirement. The worst affected health authority area is Redbridge and Waltham Forest, with nearly 10 per cent of its GPs aged 64 or over. (Hansard , 13 July, column 675w)
