Westminster is racing with rumours about who will be the next MPs to jump ship and join the anti-Brexit Independent Group bandwagon.
Seven Labour MPs — Luciana Berger, Gavin Shuker, Chuka Umunna, Ann Coffey, Mike Gapes, Angela Smith, Chris Leslie — announced their resignation from the Labour Party on Monday, followed by Joan Ryan on Tuesday.
On Wednesday three Tory Remainers — Anna Soubry, Heidi Allen and Sarah Wollaston — joined them.
So will the Independent Group become a dirty dozen?
And how many more might join?
Justine Greening
The Conservative MP for Putney in London has been sulking on the backbenches for some time.
The former Education Secretary resigned from the cabinet last year after the prime minister attempted to reshuffle her.
In October she expressed interest in launching a leadership bid if May was ousted, insisting that "things need to change" in the UK, not just with regard to Brexit.
But as Boris Johnson and the ERG became increasingly powerful within the Tory Party it has become clear a Remainer could never hope to become leader.
Greening, one of a handful of openly gay Tory MPs, might consider joining the Independent Group and could even become their leader.
Liz Kendall
The same could be said about Labour's Liz Kendall — a rising star under Gordon Brown, her career nosedived after her catastrophic tilt at the leadership in 2015.
Five of the seven original Labour splitters had voted for Kendall in that leadership election, so it would be quite appropriate if she joined them in the IG.
On Wednesday she tweeted that she had "no intention of quitting" and was focused on stopping a no deal Brexit.
If she fails, it would not be a major surprise if the 47-year-old MP for Leicester West abandoned Labour later in the year if Corbyn remains as leader.
Dominic Grieve
The Conservative former Attorney General has fallen out of favour since David Cameron left 10 Downing Street and his Remainer instincts have become an increasing liability as Theresa May's party drifted further towards a hard Brexit position.
