"Misleading Parliament is the highest constitutional crime" would also apply to the cover-up of the failed Trident test, by PM May, just before the MPs' vote on the Trident's missile programme.
North-east Somerset MP Jacob Rees-Mogg demands an inquiry into the accusation of Prime Minister was plotting with the boss of Serco, Rupert Soames, Churchill's grandson, for the UK to remain in the EU. It was dated 11 February which was before Mr Cameron had finished his renegotiating campaign.

PLEASE BE SO KIND AND CLICK ON ADVERTS. THANK YOU
Apparently if it is true "Parliament was misled". He added further: "Misleading Parliament is the highest constitutional crime.
"So if it can be proved this has happened, of course anyone has to go if they've mislead Parliament. It is a basic principle of the constitution."
Mr Rees-Mogg pointed to the Profuma Affair in the 1963 which brought down the Harold MacMillan's government It was not because Profuma had an affair but he misled Parliament.
"And I think we need an inquiry to find out what whether this was going on, we need to see the emails from David Cameron."
In my opinion that is where the saga ends. David Cameron and Downing Street will do anything to prevent the emails been given. Has the David Cameron not already prevented his emails between Brooks and himself to be included from the phone-hacking inquiry.

Has he not also denied being involved in the Panama Scandal but then admitted it when his father was named.

"He clearly has been less than honest with virtually everybody including the House of Common."
Boris Johnson commented: "This is the biggest stitch-up since Bayeux Tapestry."
Mr Johnson fumed further: "It stinks to high heaven. FTSE100 chiefs are seeing their pay pocket soar while uncontrolled immigration is forcing down wages for British workers.
"Now we learn that some fat cats have been secretly agreeing to campaign for Remain while angling lavish Government contracts.
"It makes us look like a banana republic. Probably it is also now beyond a doubt that the so-called renegotiation was a fiction designed to bamboozle the public.
"It was a meaningless mime, a ritual, a kabuki drama in which the outcome was utterly preordained. This is not the far-reaching and fundamental reform we were promised.
"The only safe way to take back control of our borders and our democracy is to Vote Leave on 23 June."
