Holly Willoughby and Phillip Schofield mocked Boris Johnson's leaked Partygate questionnaire on This Morning today.
It comes after a leaked Met Police questionnaire for the Partygate inquiry showed that the Prime Minister was asked basic questions which lawyers believe could easily be batted away.
The presenters were joined by commentators Nick Ferrari and Camilla Tominey as they joked that Ted Hastings and Miss Marple wouldn't have submitted such questions.
Holly had asked: "Nick, these people that got fines - did they have questionnaires? How were their parties investigated? I imagine it was a case of the police turning up, seeing it was happening and then slapping a fine on them.
"The problem with this is that it's taking forever , it's being very drawn out when it's perfectly obvious that this was happening."
Laughing, Nick replied: "Holly, it's not exactly Line of Duty is it?"
"No, it's not," Holly replied firmly.
Nick quipped: "It's not Ted Hastings or Adrian Dunbar submitting these questions or even the Sweeney for older viewers - 'Get your trousers on, sonny, you're nicked!'"
Phil exclaimed: "It's not even Miss Marple!"
"She'd have it sorted," Holly joked.
"If you want to see the moment that the police force - and I believe in the police force - move to being a police service, this is the moment," Nick said. "This needed to be a proper police investigation."
The forms sent to those accused of breaking Covid regulations asked respondents to provide a "lawful exception" or "reasonable excuse" for their lockdown-busting behaviour.
The document, obtained by ITV News, are part of the evidence Scotland Yard is gathering as part of its investigation into potential law-breaking on Downing Street.
It states that those accused can provide a written statement "under caution" - making Mr Johnson the first Prime Minister to face answering police questions in this way.
Labour's deputy leader Angela Rayner said: "This is an embarrassment that for the first time in UK history we have a PM interviewed under police caution."
