A report from Buzzfeed claims that Prime Minister Boris Johnson's government is:
Exploring what the consequences would be if Johnson advised the Queen not to give royal assent to any legislation passed by Parliament delaying Brexit.
I understand that the Queen is usually expected to act on the advice of her Prime Minister, as we've seen in the last few days with her agreeing to prorogue Parliament at the PM's request, but what happens if that advice is in conflict with legislation passed by Parliament against the PM's wishes?
Is there any precedent or legislation that explains what might happen, or what has happened in the past, in this scenario?
