The Libertarian Alliance [LA].
This is an alliance between classical liberals and anarcho-liberals. It uses the longer word of "libertarian" in its title as the word, "liberal", has been largely taken over by statists, ironically the very opposite of the free traders they replaced, as the statists are protectionists, ipso facto.
The new statist liberals arose within the UK Liberal Party, from about 1870 onwards and by the 1930s they were, by far, the great majority in the Liberal Party. The statists, who want more state activity, as they feel there is not enough politicians or enough politics in society but the traditional, or the pristine, liberals always felt was way too many politicians and far too much state activity and that it was actually dysfunctional for both individual and for social welfare.
So today's Liberal Democrats, whom are nearly all statists, seek yet more state control but the LA members seek far less; or even none at all if they happen to be anarcho-liberals.
This is because the LA members find the state to be both uneconomic and anti-social too, as politics both wastes the money it taxes off the public and it also fosters a dependency culture that tends to sap all individual responsibility. This personal responsibility, that arises from liberty, is held by LA members to be vital to the good society.
So the main aim of the LA is social liberty; i.e. the full individual liberty that also respects, and fits in with the liberty of one and all. The means to this is both by reducing taxation and whatever the state provides, replacing it with free, or freer, institutions, to be achieved by persuading the general public, of the value of social liberty though free discussion with anyone who wants to discuss those matters with LA members but maybe more so with keen intellectuals or with outgoing extroverts who will be keen to freely discuss those matters. Thus the LA aims at repealing most of the current statutory law. It expects social liberty to allow most people, if not one and all, to flourish to the extent that they can do so as a result a freer society, if not immediately of a completely a free one. The more liberty we have the better for all people.
The LA holds public meetings, that are recorded and then placed on YouTube and the LA members take part in its own and in other Internet discussion groups to that end.
