As for the London trip, I think it is possible that he’s seeing lawyers to initiate civil proceedings.
I doubt it.
You don't go from hiring literally THE closest lawyer down the dirt-track to some international engagement in London. He's a cheap-ass remember! There is no way on earth he can afford libel proceedings in the UK against multiple people all round the world, especially at London rates.
He'll probably be doing a tour to shake down and squeeze donations out of anyone still loyal enough, and to probably find someone to cheat on his wife with.
Remember - his family are convenient props when he wants to complain about the effect of criticism and to fundraise, but they are there to be abandoned when he wants something else.
That something else always appears to be money and sex.
He should really come with a health warning, maybe he could get a new T-Shirt printed? Something like "Warning, I sleep with Thai hookers, get checked for STDs after use"
