"Project managers who believe that closing down a project will wreck their careers are tempted to carry on in the hope they will have a slight chance of saving their reputations. Both courses carry the risk of disaster for those responsible for a project, but one—abandonment—is often far better for the company."

"There is a proper role for referendums in constitutional change, but only if done properly. If it is not done properly, it can be a dangerous tool. The Chairman of the Public Administration Committee, who is no longer in the Chamber, said that Clement Attlee—who is, I think, one of the Deputy Prime Minister's heroes—famously described the referendum as the device of demagogues and dictators. We may not always go as far as he did, but what is certain is that pre-legislative referendums of the type the Deputy Prime Minister is proposing are the worst type of all. ¶ Referendums should be held when the electorate are in the best possible position to make a judgment. They should be held when people can view all the arguments for and against and when those arguments have been rigorously tested. In short, referendums should be held when people know exactly what they are getting. So legislation should be debated by Members of Parliament on the Floor of the House, and then put to the electorate for the voters to judge. ¶ We should not ask people to vote on a blank sheet of paper and tell them to trust us to fill in the details afterwards. For referendums to be fair and compatible with our parliamentary process, we need the electors to be as well informed as possible and to know exactly what they are voting for. Referendums need to be treated as an addition to the parliamentary process, not as a substitute for it."

"Nobody has ever pretended that this will be easy. I have always said that this negotiation will be tough, complex and, at times, confrontational."

"You can change the leader, you can't change the numbers. We've got to focus on the issue here, which is delivering on the Brexit demand of the British people. That means leaving the customs union and leaving the single market."

"[E]very law we write must be written on the presumption that it will be a government very unlike ours who will be in charge at some point in the future."

"Free speech is one of our fundamental rights — it is not a gift from the state to be withdrawn at the whim of a government, but the birth right of our citizens. I sympathise with the aims of this government to maintain law and order — but that must not be at the expense of our precious rights and freedoms..."

"[On concerns over reputed rising authoritarianism in the UK] We're never going to leave the European Convention on Human Rights, despite all the waffling on about it. It's not going to happen. So there’s always that backstop."
