Duncan's 36-year-old girlfriend Nigora Whitehead, who is 32 years younger than him, said yes to marrying her beau and couldn't wipe the smile from her face following the proposal. The pair started dating around 10 months ago and have reportedly been inseparable since.
Of course, not any old location would do for the entrepreneur and businessman, so he popped the question to Nigora while the couple were enjoying a break in Monaco. Dad-of-six and grandfather-of-two Duncan got down on one knee in a Monte Carlo bar with a ring that is thought to have cost in the region of £40,000 to ask the all-important question.
The ring appears to be similar in design to the Soleste Pear by Tiffany, which is a diamond-encrusted tear drop shape that starts at £11,500 for the smallest size - with Nigora's looking nearly four times bigger.
The proposal was caught on camera, with images of the pair showing them both to be delighted by the exciting moment. Nigora uploaded a sweet collage of her and Duncan during and after the big question, saying, 'Every story is beautiful, but ours is my favourite! @dbannatyne Love you forever ❤️'

He uploaded a picture of the pair to tell fans and followers, 'We are now officially engaged.'
Duncan and Nigora met when he visited the Harley Street Dental Clinic where Nigora was working as a 'coordinator'. It is thought that she had previously worked as a Russian and Uzbek translator too, and has a degree in chemistry.
This will be Duncan's third marriage, having split from his last wife Joanne McCue in 2011, who he has two children with. Duncan also has four children with his first wife Gail, with his eldest daughter from that marriage having two children too, making him a grandfather twice.
