From Martin Wolf's FT column:
... The UK should avoid triggering Article 50: that would eliminate its leverage and would push it out of the EU within two years, probably with no further trade agreement. Any such stalemate cannot continue forever. But there could be benefits, for both sides, in avoiding too hasty and brutal an ending.
The story goes that a man condemned to death told his king: “I could teach your horse to sing, within a year.” The king replied: “Very well. But if the horse is not singing a year from now, you will be executed.” Upon the criminal’s return, his cellmate remonstrated: “You know you can’t teach that horse to sing.” He replied: “I have a year I didn’t have before. A lot of things can happen in a year. The king might die. The horse might die. I might die. “And, who knows? Maybe the horse will sing.”
I suggest we try that year or so.
