New: Parliamentarians who intend to rapidly pass legislation to stop no-deal next week see the Lords as key battleground.

Major concerns that Downing St will enlist Brexiteer peers to filibuster bill and run down the clock until prorogation.

So, some have devised a plan...

First, both Houses to sit through Friday-Sunday.

If A50 extension bill reaches Lords, a peer could lay a business motion - the first of its kind - to time limit debate for each stage of bill.

This can already happen in the Commons via ‘guillotine’ motions, but not in Lords.

Motion would be tabled after bill arrives in the Lords, either on Tuesday, Wednesday or Thursday depending on timings.

It could initially be advisory but if Brexiteers do try to filibuster it could become mandatory.

The Coalition under Cameron considered using such a device in 2011, when Labour peers threatened to filibuster legislation on boundary/voting reform.

Labour peers backed down over fears it would set v. bad precedent for Lords and could allow governments to shut down debate.

Lord Falconer, the former justice secretary, tells me: “We have the means to stop a filibuster.

“We’ve never used it before but we have also never been confronted with such a contemptuous action by a prime minister in modern times."

If this doesn't catch on, there are more tried and tested methods to stop filibustering (although their success largely depends on determination of Brexiteers).

Closure motions to end debate and progress to next stage, and 'silencing' motions, to stop those filibustering.
