We saw the PM awkwardly squirting something into a sample bottle. There will be many twists and turns before that crunch moment is reached.

Every now and again the PM shook his head in wonder. Mr Johnson may also propose new constitutional compromises.
Mr. Johnson will probably not win a referendum.
