The opposition leader plans to spearhead the process tomorrow should Mrs. May refuse to set a date, with the new threats coming just days after the embattled prime minister survived a vote of no confidence last Wednesday.

The fresh challenge comes as Mrs. May is set to reveal her Cabinet's plans to prepare for a hard Brexit.
British state secretary for Business, Energy and Industrial Strategy Greg Clark has not ruled out a second referendum if the prime minister's deal is voted down by Commons.
Parliament should be "invited to say what it would agree with", he continued, adding that he would give MPs a range of options to choose from.
However, many on Twitter have mounted both sides of the pro and anti-Corbyn camp following speculation that he had already seen a copy of the prime minister's statement and that his plan would backfire, which, it presumably did as the prime ministered declared 14 January as the official date for a 'meaningful vote' on Brexit.
If Corbyn didn't get an advance copy of May's statement, why did he thank her for an advance copy of her statement?

Corbyn — 'they've been dragged kicking and screaming to announce a date to restart the debate' — 'there can be no further attempts to dodge accountability '…so has he changed his mind about motion of no confidence?

A terrible cynic might speculate that Corbyn’s office had a fair idea that the PM would indeed announce a date for the vote in her speech, given they get to see the speech in advance 🤨

Corbyn says Govt dragged kicking and screaming into announcing date for Brexit vote. And then he…fails to demand vote of confidence.
Looks like indecision is now characterising both sides
