I worry about such proposals, because they could create a vehicle for making vexatious claims during a campaign as a way of trying to smear the opposition, whether they were making legitimate or illegitimate comments. The whole point about democratic campaigning in any election, as we all know well, is that if someone says something that we regard as an egregious slur on us, or our party, or on reality—it does not matter—the answer is not to run to the lawyers but to get out there and explain to the voters why what has been said is entirely wrong.
The country has voted to leave the EU. Whether we in this room individually agree with it or not, the decision has been made. If we now decide that we will not leave after all, and that we will hold another referendum instead, the outrage at an out-of-touch political class, deaf to the desire of the people who elected them, will be absolutely shattering.
