A senior Downing Street source said: "The government will comply with the Benn Act, which only imposes a very specific narrow duty concerning Parliament's letter requesting a delay - drafted by an unknown subset of MPs and pro-EU campaigners - and which can be interpreted in different ways.
"But the government is not prevented by the Act from doing other things that cause no delay, including other communications, private and public.
"People will have to wait to see how this is reconciled. The government is making its true position on delay known privately in Europe and this will become public soon."
This quote is so misleading, Cummings (who is almost certainly the source) is either spreading misinformation or is totally oblivious to the law. Both equally probable.
The first paragraph is wrong - the Benn act is well thought out and well written, it's not open to debate what any of it means, it's not narrow and it's authorship is irrelevant. The Government can't get around it by saying it isn't clear, it is.
The second paragraph is misleading, it is correct to say that the Benn act doesn't implicitly prevent any of those actions, but the law already does. The Government can't frustrate the contents of that letter without breaking the law.
The third paragraph is absolute nonsense. Nothing more needs to be said about it.
