Didn't Mosley's British Union have the same idea?
Thanks for the question, which prompted me to read Mosely's short book 'The Greater Britain'.
There are similarities between the BUF and the Front National's programmes but - in the most brutal terms - the absence of WWII in one and the experience of invasion and slavery by a fascist army in the other shines through. The FN remain for the time being a republicain, democratic party willing to be voted out of office.
There are great quotes in the Mosely book. It seems to be the origin of the 'Britain First' party name. This is...prophetic;
At the end of that franchise a new election will be held on an Occupational Franchise - a steel worker will vote as a steel worker, a doctor as a doctor, a mother as a mother - within their Corporation.
