Report from ITV's Robert Peston
"I am reliably told Theresa May won't put a date on how long she needs to renegotiate Brexit plan and therefore MPs won't know when they will finally get their vote. This undated extension of talks will be no more acceptable to MPs than her undated Backstop," Peston reports.
He's a reliable reporter and says the open end-date will lead to the usual anger and consternation from the usual quarters.
He notes that the real deadline is January 21 when she must present a Brexit plan to parliament.
