a century it has remained unchallenged as the best biography and is rightly regarded as a classic". Like Healey and Crosland, he had been a close friend of Hugh Gaitskell and for them Gaitskell's death and the elevation of Harold Wilson as Labour Party leader was a setback. For Jenkins, Gaitskell would remain his political hero. After the 1964 general election Jenkins was appointed Minister of Aviation and was sworn of the Privy Council. While at Aviation he oversaw the high-profile cancellations of the BAC TSR-2 and Concorde projects (although the latter was later reversed after strong opposition from the French Government). In January 1965 Patrick Gordon Walker resigned as Foreign Secretary and in the ensuing reshuffle Wilson offered Jenkins the Department for Education and Science; however, he declined it, preferring to stay at Aviation. Home Secretary (1965–1967) In the summer of 1965 Jenkins eagerly accepted an offer to replace Frank Soskice as Home Secretary. However Wilson, dismayed by a sudden bout of press speculation about the potential move, delayed Jenkins' appointment until December. Once Jenkins took office – the youngest Home Secretary since Churchill – he immediately set about reforming the operation and organisation of the Home Office. The Principal Private Secretary, Head of the Press and Publicity Department and Permanent Under-Secretary were all replaced. He also redesigned his office, famously replacing the board on which condemned prisoners were listed with a fridge.

The Times called it "the greatest upheaval in policing since the time of Peel". His visit to Chicago in September (to study their policing methods) convinced him of the need to introduce two-way radios to the police; whereas the Metropolitan Police possessed 25 radios in 1965, Jenkins increased this to 2,500, and provided similar numbers of radios to the rest of the country's police forces. Jenkins also provided the police with more car radios, which made the police more mobile but reduced the amount of time they spent patrolling the streets. His Criminal Justice Act 1967 introduced more stringent controls on the purchase of shotguns, outlawed last-minute alibis and introduced majority verdicts in juries in England and Wales. The Act was also designed to lower the prison population by the introduction of release under licence,
