You've posted this before. It's from before Cameron started his own EU negotiations, when he was making his own threats to the EI in the hope of getting concessions. This was well before he triggered the referendum and well before the Leave EU led their campaign promising:
"Taking back control is a careful change, not a sudden stop - we will negotiate the terms of a new deal before we start any legal process to leave"
This was the promise made by the campaign leading the persuasion for people to leave the UK during the referendum. It was from their blinking manifesto. How much clearer does it need to be!:
