"The shadow Brexit secretary (Sir Keir Starmer) doesn't support Brexit, the shadow foreign secretary (Emily Thornberry), the shadow chancellor (John McDonnell) doesn't support Brexit, the Labour deputy leader (Tom Watson) doesn't support Brexit.

"Labour wants to block Brexit and that would be a betrayal of the many by the few."
