The Centre for Policy Studies (CPS) is a think tank and pressure group in the United Kingdom. Its goal is to promote coherent and practical policies based on its founding principles of: free markets, "small state," low tax, national independence, self determination and responsibility. While being independent, the centre has historical links to the Conservative Party. It was co-founded by Sir Keith Joseph, Alfred Sherman and Margaret Thatcher in 1974 to challenge the post war consensus of Keynesianism, and to champion economic liberalism in Britain. With this in mind Keith Joseph originally wanted the think tank to study the social market economy, naming it the 'Ludwig Erhard Foundation' and 'Institute for a social market economy' until it was eventually settled on the benign 'Centre for Policy Studies'.The centre has since played a global role in the dissemination of free market economics alongside policy proposals claimed to be on the basis of responsibility and individual choice. It also asserts that it prioritises the concepts of duty, family, liberty, and the rule of law. The CPS states that it has a goal of serving as "the champion of the small state."

The Delegation of the European Union to the United Kingdom, formerly known as Representative of the European Union (specifically the Representative of the European Commission and the Representative of the European Parliament) in London are the diplomatic missions of the European Commission and the European Parliament in the United Kingdom.They are both located in Europa House, 32 Smith Square. The building was formerly the Conservative Party's Central Office from the late 1950s until 2004 and was famous as the place where the Conservatives planned and celebrated their election victories. It was then left vacant until 2009 when the EU chose it as their new London office, along with a new personalised postcode – SW1P 3EU. There was some criticism of the amount spent by the EU in acquiring and updating the interior of the building, with £20 million spent on purchasing the property and £5 million on revamping the building. It allegedly included the installation of bomb and bullet-proof windows.As a result of the United Kingdom's withdrawal from the European Union on 31 January 2020, the Representative of the European Union was replaced by the Delegation of the European Union to the United Kingdom Since February 2020, the Ambassador of the Delegation of the EU to the UK has been João Vale de Almeida. The representative is referred to as ambassador, however in the United Kingdom full diplomatic status is only given to representatives of sovereign states.

55 Tufton Street is a four storey Georgian era townhouse on Tufton Street, in Westminster, London, owned by businessman Richard Smith. Since the 2010s the building has hosted lobby groups and think tanks related to Brexit and climate change. A group of these think tanks, dubbed "The Nine Entities", use the building for biweekly meetings to coordinate policy and public messages.The nine lobby groups—the TaxPayers’ Alliance, the office of Peter Whittle (the former deputy leader of UKIP), Civitas, the Adam Smith Institute, Leave Means Leave, the Global Warming Policy Foundation, Brexit Central, the Centre for Policy Studies and the Institute for Economic Affairs—were accused by former Vote Leave employee Shahmir Sanni of using the meetings to "agree on a single set of right-wing talking points" and "securing more exposure to the public".The organisations it houses have close connections with those at nextdoor 57 Tufton Street, including the Centre for Policy Studies and CapX.

Tufton Street is a road in Westminster, London, located just outside of the Westminster Abbey precinct.

The European Foundation is a leading Eurosceptic think tank based in the United Kingdom, founded in 1992. It is chaired by Bill Cash, a British Conservative MP. The organisation produces the European Journal. The Great College Street Group was formed in October 1992 in order to oppose the Maastricht Treaty. The Group, consisting of politicians, academics, businessmen, lawyers, and economists, provided comprehensive briefs in the campaign to win the arguments both in Parliament and in the country. The European Foundation was created out of Great College Street by Bill Cash after the Maastricht debates. It exists to conduct a vigorous campaign in the UK to leave the European Union. The Foundation continues to establish links with like-minded organisations across Europe and the world. It was reported in 1996 that the European Foundation was being funded by Sir James Goldsmith the then leader of the British Referendum Party. Because there was an approaching election at which Conservative and Referendum candidates would be contesting the same seats, Cash was forced to sever the link. The shortfall in funding was plugged by Margaret Thatcher, who later became the European Foundation's Patron, a position she held until her death.
