"Its list of Vice-Presidents included Professor Antony Flew, Professor Tryggvi McDonald, Rev.

The Directorate consisted, until the mid-1990s, of Andrew Smith, Stuart Notholt, Gideon Sherman (son of Sir Alfred Sherman), and others."

Notable activities
"WGI supported the continuance of apartheid policies in South Africa, and hosted a visit to the UK, in June 1989, by the hierarchy of the Conservative Party of South Africa, a hard-line breakaway from the National Party of South Africa, including its leader Dr. Andries Treurnicht. A press conference was held for the delegation in a committee room of the House of Lords on 5 June[10]. Conservative Party of South Africa MP Clive Derby-Lewis, then a member of the State President's Council, was made an honorary vice-president of the WGI. Western Goals may have supported the anti-communist cause with more than rhetoric. The United Nations High Commissioner for Refugees (2 July 1993) lists the Western Goals Institute as an "impediment" to the elimination of racial discrimination in South Africa, saying of the Institute that it "claims to be devoted to protecting the Western way of life by offering self-defence training to white South Africans"[11].
On 25 September 1989, Baron Sudeley chaired a Western Goals dinner at Simpson's-in-the-Strand for El Salvador's President, Alfredo Cristiani, and his inner cabinet. The guest list included figures such as Sir Alfred Sherman (policy advisor to Margaret Thatcher), Nicholas Hervey, Antony Flew, Zigmunt Szkopiak, Denis Walker and Harvey Ward[12].
In Europe, Western Goals gave their open support to the French Front National, the populist far-right political party led by Jean-Marie Le Pen. On 12 October 1989, WGI hosted a controversial fringe meeting at the Conservative Party Conference in Blackpool, addressed by Front National Member of the European Parliament, Pierre Ceyrac. Western Goals also examined the possibility of links with the hard-right German party The Republicans, which in 1989 had six members in the European Parliament.
On 12 August 1989, a delegation from the Western Goals Institute attended a large anti-communist demonstration at Moln, near Lübeck, where 20,000 people had gathered. It was organized by Die Deutschen Konservativen e.V., which was led by another media personality, Joachim Siegerist, now a parliamentarian in Riga, with whom the WGI had contacts.[7]
The group hosted social events including an Annual Dinner at the Grosvenor Hotel at Victoria on 24 November 1989 when the guest of honour was Kenneth Griffith, who spoke out against non-white Third World immigration into Britain and Europe. On 20 November 1990, they hosted the General Franco Memorial Dinner, commemorating the anniversary of his death. This was also chaired by Baron Sudeley. A WGI notice in The Times stated that the late ruler of Spain was "remembered as a hero against communism". "

en.wikipedia.org/wiki/Conservative_Monday_Club
"In October 1982, the Monday Club published its latest, slightly revised, policy on immigration. It called for:
Scrapping of the Commission for Racial Equality and Community Relations Councils.
Repeal of the race relations laws.
An end to the use of race or colour as criteria for the distribution of state benefits & loans.
An end to positive discrimination and all special treatment based upon race or colour.
An end to all further large-scale permanent immigration from the New Commonwealth.
An improved repatriation scheme with generous resettlement grants for all those from New Commonwealth countries who wish to take advantage of them.
The redesignation of the Ministry of Overseas Aid as a Ministry for Overseas Resettlement.
The club's position on immigration was reiterated in a letter in The Times from Lauder-Frost on the club's behalf in October 1991 where he stated that the annual levels of immigration "were unacceptable" and called for "the strictest possible entry to Britain for those of other cultures."[55]
Northern Ireland
Following an Official Irish Republican Army (IRA) bombing at Aldershot, Hampshire, in February 1972, club member and MP Jill Knight called for legislation to outlaw the Official IRA and its political wing, Official Sinn Féin. The club was opposed to the dismantling of the Stormont government in Northern Ireland and the imposition of direct rule.[56] On 7 September 1989, Lauder-Frost, on behalf of the Club, denounced "the disgraceful Anglo-Irish Agreement" in The Sun.
Controversies and criticism
The Guardian claimed in 1968 that the organisation was "probably the nearest British equivalent to the American John Birch Society".[57] It was claimed by opponents of the club that many members had drawn closer to the National Front, it being reported as early as 1973 that NF members were moving to take over branches of the club.[58] The bad publicity led to a crisis culminating in a series of purges, mainly in Club branches.[59]
In his Diaries, Alan Clark describes speaking to the Monday Club in 1982: 'I really cannot bear the Monday Club. They are all mad, quite different from its heyday, when it was a right-wing pressure group at the time of Ted Heath's Government. Now they are a prickly residue in the body politic, a nasty sort of gallstone.' [60]
The playwright David Edgar described the Monday Club, in 1986, as "proselytis[ing] the ancient and venerable conservative traditions of paternalism, imperialism and racism."[61]"
My conclusion wrt Brexit - no idea emerges in a vacuum.
