The specific dynamics of the London health care labour market, and the challenges they create for recruitment and retention, were highlighted in the 2003 King's Fund report 'In Capital Health?'. In the 18 months since, a number of important and far reaching changes have been initiated across the NHS.

It also looks at the challenges lying ahead and some possible ways forward. [Introduction abbreviated]
