Interesting - Some weeks ago I spent an unpleasent hour or so digging thru various "Ultra right" websites trying to get some hint as to what the "Facists" were up to here in Old South Wales ( We had just had an outbreak of the classic Facist preparatory tactics before local elections ie Anon letters stating that your house was to be compulsary purchased for asylum seakers etc).
Google found "Stormfront" for me on a Welsh/Celtic cross reference.
It is well documented that various versions of early Nationalist Parties were proto facist. I can not speak for the Scots, but in Wales, Saunders Lewis, the founder of Plaid Cymru was well on record as being an admirer of Hitler and Franco.
I have before me a leaflet issued by the BNP supporting thier candidates for Wales playing very heavily on the Celtic conection, tho I feel from the flow of the leaflet this may have been inserted into an "English" aimed leaflet.
Other Facist leaflets which have come into my possesion (for Party reasons) and trawls through thier website indicates an attempt in North Wales to blame the influx of English speaking "immigrants" to North Wales on the "English being driven out of England by (insert the appropriate invective).
My best judgement is that this will not be productive, but it gives an indication of the trend.
I can not claim that this is a first class analysis, but I think it shows a trend.
Further information, particullaly in the Irish conection can be found at that excellent source of information on the "Ultra Right" Searchlight
