I will give way in a moment.
The Prime Minister has announced that he will suspend the rules of collective responsibility and that members of the Government will be able to campaign on whichever side they choose. We now have the letter giving an undertaking that the Government will depart from section 129. People seem to think that there is something magic about 5 May 2016, so we will not hold the referendum on that date. I have sympathy with Ministers; they are being derided. The moment they make concessions to all these impassioned pleas, they suffer the fate of all Ministers and are immediately accused of a humiliating U-turn and held up for ridicule.
Some of my right hon. and hon. Friends and perhaps others in the Scottish National party are difficult to calm down and reassure. I ask them to accept, as I accept, that every effort is being and should be made to satisfy fears about the propriety of the campaigning period.
