speech in 1988, in which she declared that "we have not successfully rolled back the frontiers of the state in Britain only to see them reimposed at a European level". A number of free-market Conservatives have signed the Better Off Out pledge to leave the EU. Thatcherites and economic liberals in the party tend to support Atlanticism, something exhibited between Margaret Thatcher and Ronald Reagan. Thatcher herself claimed philosophical inspiration from the works of Burke and Friedrich Hayek for her defence of liberal economics. Groups associated with this tradition include the No Turning Back Group and Conservative Way Forward, whilst Enoch Powell and Keith Joseph are usually cited as early influences in the movement. Some free-market supporters and Christian Democrats within the party tend to advocate the Social Market Economy, which supports free markets alongside social and environmental responsibility, as well a welfare state. Joseph was the first to introduce the model idea into British politics, writing the publication: Why Britain needs a Social Market Economy. Relationships between the factions Sometimes two groupings have united to oppose the third. Both Thatcherite and Traditionalist Conservatives rebelled over Europe (and in particular Maastricht) during John Major's premiership; and Traditionalist and One Nation MPs united to inflict Margaret Thatcher's only major defeat in Parliament, over Sunday trading. Not all Conservative MPs can be easily placed within one of the above groupings. For example, John Major was the ostensibly "Thatcherite" candidate during the 1990 leadership election, but he consistently promoted One-Nation Conservatives to the higher reaches of his cabinet during his time as Prime Minister. These included Kenneth Clarke as Chancellor of the Exchequer and Michael Heseltine as Deputy Prime Minister. Electoral performance and campaigns National campaigning within the Conservative Party is fundamentally managed by the CCHQ campaigning team, which is part of its central office However, it also delegates local responsibility to Conservative associations in the area, usually to a team of Conservative activists and volunteers in that area, but campaigns are still deployed from and thus managed by CCHQ National campaigning sometimes occurs in-house by volunteers and staff at CCHQ in Westminster. The Voter Communications Department is line-managed by the Conservative Director of Communications who upholds overall responsibility, though she has many staff supporting her, and the whole of CCHQ at election time, her department being one of the most predominant at this time, including project managers, executive assistants, politicians, and volunteers.
