Johnson has proposed a "European Commonwealth" of the UK, Ukraine, Poland, Baltic States & later Turkey that would be an "alternative to the EU [for] countries united by distrust of Brussels and Germany's response to Russian aggression",
I suspect that he realises the tide is turning against the Brexit he's delivered. So he's darting ahead of the crowd and shouting 'follow me', in Heseltine's words. Similar ideas of an inner and outer EU have been put forward before, and Cameron for one rejected the idea, wanting to be 'at the top table'.
Poland and the Baltic States are already in the EU. I doubt whether they will want to leave. Turkey - well it's been trying to join for 40 odd years with no success. Would they want some half cock alternative - I suspect not.
So is this Johnson's way of trying to bring the idea of the EEA back onto the table? Or was it just 'how do I save my skin'? Partygate hasn't died down as it should. Rishi Sunak's U turns are just stealing Labour's clothes, and have been met with cynicism, rather than rapturous applause. Meanwhile more and more Tory MPs are putting their letters in - whether on principle or because they want to save their seats - who knows?
