The 52-year-old BBC newsreader recently told the Radio Times she was willing to break the coronavirus restriction on households mixing so she could have both her parents over for Christmas.
Now Derbyshire has now said on Twitter: “I’m starting the day by saying I’m sorry: a few weeks ago the Radio Times asked me (amongst other things) what would potentially happen at Christmas with my own family if the rule of six was still in place....
“I talked about my mum, her partner & my dad-in-law spending it with us – making seven in our home in a Tier One area (medium). It was hypothetical – however I was totally wrong to say it & I’m sorry. We’ll of course continue to follow whatever rules are in place on Dec 25th.”
Government restrictions currently prohibit groups of more than six people from different households gathering indoors in a Tier 1 area.
In Tier 2 and Tier 3 areas households are not permitted to mix indoors, while groups of six people or fewer are permitted to meet outdoors only.
The Lancashire-born journalist and mother-of-two had previously told the Radio Times: "If the rule of six is still in place... we're breaking it to have the rule of seven. We just are."
She went on: "It's fine. We'll do it knowing what the risks are. We're not stupid.
"We're going to be sensible and buy a thermometer gun. But we have to be together at Christmas.
"It feels almost irresponsible saying that, but I don't think we're alone in feeling that way.
"We need to see my elderly mum and my husband's elderly dad. We just do."
A study published this week by the London School for Hygiene and Tropical Medicine (LSHTM) found that the rule of six and 10pm pubs curfew had “zero effect” on coronavirus transmission.
