Rab was one of the founders of One Nationalism (hardly a plus for me) and a social progressive. Like Wilson he will try to liberalize social legislation- relax divorce law, decriminalize homosexuality and abortion, and remove the remnants of press censorship. Abroad he will push for decolonization, though like all Tory PMs except Heath Rab was an Atlanticist/Commonwealther. On the economy- the usual One Nationalistic Keynesianism, but in the early 1960s it won't make that much of a difference. What he would do about Rhodesia is uncertain- would Smith declare UDI under a Tory government. Rab would face strong opposition from the party right on social questions (senior neoliberals were then only Powell and Thorneycroft)- among others the then-backbencher Margaret Thatcher. They would want to keep the social laws as is, excepting homosexuality, though not out of pro-gay rights feelings, rather due to unenforceability. Polaris probably is acquired. TSR2 and CVA-01 might be kept. Perhaps the Arrow is procured from Canada. There isn't enough money in the defence budget for all 3, so they'd have to choose. Rab would be implacably opposed by Macmillan on personal rivalry grounds, which means he keeps the Chancellorship. The only other Chancellor would be Thorneycroft, who's a monetarist and a pioneer of the neoliberal wing of the Tory Party. Since No 10 and No 11 need to be on the same page regarding monetary policy, the One National, Keynesian Macmillan stays Chancellor. Fyfe would become Home Secretary, Home Foreign Secretary and DPM. Heath and Reggie Maudling get senior economic posts- or Heath becomes Leader of the House and Maudling at the DTI.
