Above is the latest polling on Johnson and this is in line with other earlier surveys that we have seen. By a very clear margin voters, including 38% of Tory voters want him out.
On Wednesday there are likely to be further developments and, of course, Johnson will have to face Starmer at PMQs.
These are couple of betting markets from Smarkets.
Note- we are having issues with Vanilla which means the commenting system is down. Hopefully, this will soon be restored
