Dr Mark Porter has cleared up confusion over the government's new lockdown rules.
Under Boris Johnson's latest guidelines, groups of six from two different household are now allowed to meet up.
But Good Morning Britain viewers were left with unanswered questions from the prime minister.
GMB fans confused by lockdown update
Speaking on the show today, Ben Shephard and Ranvir Singh told Dr Mark that many weren't sure what the rules meant.
"One viewer has asked is it is her house plus six others because she's from a family of five," Ben said.
Dr Mark explained that this sadly isn't the case.
He said: "In theory, my understanding of the rules is that it's six people from two households – so four from one and two from the other or whatever.
"But it's six people in total. It's obviously different if you're living in Scotland. It's eight in Scotland and there's no limit in Wales.
"So it's my understanding that you're only allowed one guest."
Dr Mark Porter explains latest guidelines
Ranvir then pointed out that you could still abide by the law while seeing more than five others.
The host explained that she could meet with one group of five in the morning and then another in the afternoon as this wouldn't be breaking the rules.
Dr Mark stressed that wasn't an attitude he wanted to encourage, however.
He said: "Technically, yes but this is about keeping within the spirit of the rules and that would really defeat the object if you said right I'm going to see that household at 11, that household at 1pm.
From Monday (Jun 1), groups of six from wo different households will be allowed to meet as long as it's outside – which includes gardens.
Under the new guidelines, barbecues will be permitted but hygiene advice and social distanced still need to be adhered to.
No change for the vulnerable
Sadly, the new guidelines do not apply to the most vulnerable people in society.
Dr Mark added: "The rules for shielding are not changing.
"They will remain the same until the end of the month. It's sad but it's for their own protection – at the moment, stay at home please."
Good Morning Britain is on ITV, weekdays at 6am.
