Nadiya Hussain: 'You've got to feel some pressure when it's the Queen, right?'

Nadiya made the Queen an orange drizzle birthday cake over four days, and used 42 eggs to create the three-tier confection which actually featured 12 cakes.

She said: "My theory was if lemon drizzle was good enough for Mary Berry, we can change it up and do one for the Queen."

The baker added that she froze when she first spoke to the Queen but recovered: "She asked me about what was in the cake, because she said 'Does it cut?', so clearly she's had issues about cutting cake - hence why I didn't do a fruit cake."

She added: "You've got to feel some pressure when it's the Queen, right? Every time I tried to ignore the fact I was doing it for the Queen, my husband would very conveniently remind me - 'Hey, hey, you're slacking. It's for the Queen. Get up, you can't be lying down'."

And it appears the Duke may be an avid watcher of the BBC's hit baking show, Ms Hussain suggested.

"The Queen said 'Oh, she won the baking show' and he said 'Of course I know she won the baking show' - I think they were having a bit of a conversation."

A decade on from her 80th the Queejn used an open-top state review vehicle to complete the last part of her public appearance and she and Philip were driven through Windsor past the crowds.
