If Lil' Rish! weren't so pathetically weak, he should be sacking Braverman as Home Sec - you cannot have a Cabinet member, less still one (somehow) holding the great offices of state, openly briefing against party policy - and taking the whip off Johnson, being as he keeps fucking off overseas, is clearly only interested in trying to get back into power, virtually never attends Parliament (might have changed very recently, but when I checked a couple of weeks ago, he hadn't voted on anything since September), broke rules on paid outside employment, went to Kyiv pretending to be Foreign Secretary and fuck knows what he promised with zero authority, and again is undermining the Government.
But he is pathetically weak so it'll carry on.
He's only going to get one go at being PM and not even a full term of it. You might as well do it your own way. And while there's virtually no hope of winning a GE, if you managed to end Johnson's appalling political career permanently, you'd get at least a begrudging nod in the history books, in fact it would make him the best PM since 2010 all on its own.
