Deer's investigation led to the longest-ever inquiry by the UK General Medical Council (GMC). In January 2010, the GMC judged Wakefield to be "dishonest", "unethical" and "callous", and on 24 May 2010, Wakefield was removed ("struck off") from the UK medical register. Responding to Deer's findings, "The Lancet" partially retracted Wakefield's research in February 2004, and fully retracted it in February 2010 following the GMC findings. In 2011, Deer published his findings in the "BMJ" with an endorsement by the editors.
