It seems that Gavin Webb may be setting up a libertarian party.
Gavin is a former member of the Lib Dems who left to join the UK Libertarian party.
Presumably, this new party won't be called the Libertarian party. It is unclear for now what it will stand for, what it will aim to do and what its objectives will be.
Update - since posting this, it seems that the new party has been stopped in its tracks by the old party.
