The £1 Billion per month is made up of 3 and a bit times the £350 million that we pay to the EU per week.
The fact that it also chips away at the £39 billion that we have also agreed, or that the £350 million was a lie is neither here nor there, £1 Billion is a big number, as any fule knoes
Obviously not even believing his own government's briefing or the head of Dover (experts >>) who forecast losing £1bn a week. Twat.
