The dad of Britain's biggest family has shown off a massive pie he made to feed his children.

Noel Radford compared the gigantic pie to a normal sized one on his Instagram page.

He posted the snap of the pie on Friday, which would take others a week to get through.

Noel shared a picture of the finished pie, placing a bottle of coke an a regular sized pie on either side to compare the huge size difference.

He captioned the photo: “Regular pie versus a family pie for us.”

The Radfords have previously stated a standard pie made at their bakery would weigh 280g, whereas a pie large enough for their family would be at least 1850g.

They own a bakery which specialises in pies and ships them to customers around the UK.

Noel and his wife Sue, both 45, gave birth to their 22nd child Heidi in April, while their eldest child is in his 30s.

The family, from Lancashire, include kids Chris, 31, Sophie, 26, Chloe, 24, Jack, 22, Daniel, 20, Millie, 19, Luke, 19, Katie, 17, James, 16, Ellie, 15, Aimee, 14, Josh, 12, Max, 11, Tillie, nine, Oscar, eight, Casper, seven, Hallie, four, Phoebe, three, Archie, two, Bonnie, one, and five-month-old Heidie.

And the family is even larger – with eldest son Chris having two children of his own, daughter Sophie has three children, and 19-year-old Millie has one of her own.

The family document their lives online – with over 323,000 followers on Instagram and over 225,000 subscribers on YouTube.

Meanwhile, one-year-old Ophelia, daughter of Millie Radford, left heads turning as she appeared to make a very rude gesture.

Millie shared a video of her appearing to flick the bird.

First-time mum Millie, 19, shared the clip on  Instagram  yesterday of the one-week-old tot.

Ophelia can be seen doing the backwards V gesture before lowering her index finger, which had Millie in hysterics.

She wrote: “Who taught you that?” followed by the crying emoji and tagging her sisters Chloe, 25, Sophie, 26, as well as mum-of-22 Sue.

One member of the family can be heard saying: "She's sticking her middle finger up!"

Ophelia weighed 7lbs and 12oz when she was delivered last Thursday.
