I think that's likely. I think that there are two possibilities here, are there not? If there's no deal, then it would be 'no deal' or remain. If there is a deal, it becomes a bit more complicated, in the sense that it's: 'Do you accept the deal? But, if you don't, what do you want: "no deal" or remain?' There are ways in which the Electoral Commission, I'm sure, can finesse that referendum. But, if there's no deal on the table, well, surely people have the right to express a view as to whether they wish to leave in circumstances that not one Brexiteer suggested would happen. Nobody said two years ago, 'If there's no deal, it doesn't matter.' No-one said it. Everyone said, 'There will be a deal.' That's changed.

I don't like the idea of a second referendum on exactly the same issue, which is why I opposed a second referendum in 1997. But, where the circumstances have changed fundamentally, where the promises that were made two years ago have come to nothing, then, at that point, and if there's an inconclusive result in a general election—. Who knows what parties might put forward in a general election? I'm sure the Lib Dems will put forward something quite different again. I'm sure his party will as well. But there has to come a point where, if there is an impasse, the people have to decide, and they have to be allowed to decide on the basis of what they know now and not on what they were told two years ago, which hasn't happened.
