If Rayner goes, as many now think is likely, the question becomes who replaces her and what will she do next?published at 07:24 BST 5 September

It feels like crunch time for Angela Rayner.
Plenty of folk at Westminster reckon today is the day her fate will be determined.
The prime minister told me yesterday he expected the investigation by the independent adviser on ministerial standards to be quick and he thought that was a good thing.
That suggests too that Keir Starmer won’t prevaricate in offering his own judgement about the report's findings once he himself has them.
As ever, there's always scope for unforeseen wrinkles or unrelated stuff that pushes things back a bit.
Does the prime minister want to do a wider reshuffle at the same time?
Aside from the timing, this is a "heads it's awkward, tails it's awkward" situation for the prime minister.
If the report leaves scope for the deputy prime minister to stay on, it’s not an easy argument to make after all the revelations of recent days.
But, as most I talk to now think is more likely, and she goes, there are then two big questions: who replaces her and what does she do next?
Does she remain deputy leader of the Labour Party, a position she was elected to by party members, even if she is no longer deputy prime minister and housing secretary?
If she resigns as the party’s deputy leader, a contest to replace her would begin.
When I spoke to Starmer in Glasgow on Thursday, he was talking up a £10bn deal to sell warships to Norway.
He talked with an enthusiasm about digital ID cards, as a potential tool for tackling illegal immigration, and about tweaks to the implications of the European Convention on Human Rights he’s determined to push through.
But all of this, inevitably, generates fewer headlines than the conduct of his deputy.
