This would make a lot of sense, I've heard stories from people which would suggest this was the case. There's also a particularly lurid story on an anonymous blog somewhere which purports to explain what SYL was up to when he developed his hatred of Muslims.
The video of Lucy Brown claiming SYL might have been spending his supporters money on chang needs to be seen in the context of split within the 'Tommy movement' over Israel/Jews. There's been a few things which have caused it and it stems from SYL losing Brown, Robertson and LLewlyn-John as his 'team' and replacing them with Daniel Thomas and Avi Yemini, which means there are no longer people within SYL's immediate circle who have sympathies for white nationalism and Zionism is far more important for them than it was even last year, although SYL has of course always been on the Zionist side of this split within the counter-jihad movement.
There's two incidents which people on the Nazi side of the split are citing as reasons for their break with SYL. One is him crowd funding large sums of money to make a documentary about Muslim grooming gangs. Apparently supporters were expecting it to be released soon but it appears to have been canned or is delayed. At one of the protests outside the Old Bailey he announced a new documentary called 'Shalom' which is due to come out soon and is about an elderly Jewish man who moves to Israel from the UK because of anti-Semitism from Muslims (supposedly). The other incident is long term SYL associate Shazia Hobbs being forced out of the TR.News editorial team after writing an anti-Semitic article for the website about the Frankfurt School (and presumably cultural Marxism). Hobbs has recently become quite chummy with former BNP youth leader Mark Collett.
The Nazi side of the split appears to be led by Collett who has been organising a number of what seem to be fairly competent young white nationalists. Collett was recently the subject of a
hit piece video released by TR.News which was released to hit back at his side after Brown's revelations. Collett's got a fairly large following on Twitter and YouTube (and has been very careful about not breaching the rules of both) and has been using this to push his politics. He's also been organising a series of IRL events, such as runs, camping trips in the Peak District and drinks in pubs. It was on one of the camping trips on the Peak District that Brown was photographed wearing a Sonnenrad necklace while walking along the Mam Tor ridge. These trips appear to have grown in size, with Collett claiming 38 people were on the last one.
Among those 38 were
former Conservative council candidate Darren Harrison from Watford, who seems to be going full Nazi, as well as his fellow
'Defend Europa' writer Laura Towler. On one of Collett's weekly YouTube shows before the whole 'Tommy movement split' happened, Collett and Towler revealed they are encouraging other white nationalists to join them in conducting a survey in white working class areas, asking people who they feel about 'being demographically replaced', which they'll be releasing a film of themselves doing titled 'We Were Never Asked'. This is fairly sophisticated propaganda for their movement and appears to be intended to get this new generation of activists familiar with going into white working class communities and talking to people, something which the BNP was fairly effective at in the past but the far-right has struggled with over the past decade.
At the moment Collett is organising a conference for this scene which will be held in the Manchester area in September. Tickets are £50 a pop which gets you a two-course meal and the opportunity to listen to a handful of speakers, capacity is capped at 100 and apparently at least half of the tickets have already gone. I would really not be surprised to see people around Collett attempt to launch a BNP 2.0 at some point in the near future. Collett was seen as a potential leader for such a party, which it looked like the Forum network was hoping to launch before it fell apart, but maybe has enough sense to realise he's too discredited to lead such an organisation himself. Irrespective of that, while SYL is in prison, it looks like Collett is making a bid for hegemony on the far-right and is trying to damage SYL as much as he can. I'd be surprised if he won this battle and imagine SYL will still be a key figure on the far-right when he is released, but his era of dominance on the British far-right appears to be on the wane.
