Wasn't someone planning a vote of no confidence a couple of weeks ago?

What happened?

There's no extension yet and a proroguing for a GE would've led to no deal by accident / design as BoZo was the one who could choose the GE date, so would've timed it to allow for no deal.

The opposition can't agree on a GNU leader, so a GE is what would've come out of a VoNC, rather than an alternate government.

It was Jo Swinson, new leader of the Liberal Democrats.
But she refuses to support Jeremy Corbyn as an alternative leader and Jeremy Corbyn refuses to accept anyone other than Jeremy Corbyn as an alternative leader.

After a Vote Of No Confidence (Assuming Boris loses) there's 14 days to vote for a new government / new leader, if Corbyn won't step aside and the Corbyn haters won't stop hating Corbyn there'll need to be another General Election.
The first problem with this is that the current prime minister gets to choose the date of a General Election and he'd set it to 1st November meaning Parliament is disbanded until then and he gets his wish for No Deal.
The second problem is another General Election before the Brexit issue is resolved would almost certainly lead to a hung parliament.

Not really, it was just the media thinking out loud.

No point in a VONC without ongoing plan, and they haven't agreed a plan. If only such wisdom and restraint had been widespread before referendum, eh? [I need an unmistakable sarcasm emoji.]
