Quoting from a live feed:

n the Commons John Bercow, the Speaker, is taking points of order ahead of the debate on the Benn bill.
Sir Bill Cash, the Tory Brexiter, asked if the bill required Queen’s consent. Cash said he was inspired to ask the question partly by this blog by Robert Craig, a public law lecturer, who suggested Queen’s consent would be required. He argued that this would be a problem.
But Bercow told Cash he had considered this matter and decided Queen’s consent was not required.
