Sir John Michael Medlicott Vereker, KCB, KStJ, FRSA (born 9 August 1944) is a former British civil servant who served as Permanent Secretary for International Development (1994–2002) and Governor of Bermuda (2002–2007).
After returning to the Ministry of Overseas Development, he was appointed private secretary to three Labour Cabinet Ministers – Reg Prentice, Frank Judd and Judith Hart.
In 1980, he was invited by the Prime Minister, Margaret Thatcher, to join her staff in 10 Downing Street, where he served for three years as a member of the small three-person policy unit established by Sir John Hoskyns, working on public sector pay, the labour market and industrial disputes.
He helped to establish the feasibility of withstanding a miner's strike, and when the detailed strategy defined by the policy unit was successfully followed, the foundation of the labour market reforms of the 1980s had been laid.
In 2002 Sir John was appointed Governor and Commander-in-Chief of Bermuda, acting as de facto head of state, with direct responsibility for ensuring the safety, security and good governance of the territory.
