Birthday buoy! Dragon's Den star Duncan Bannatyne celebrates his 75th birthday with some glamorous friends… and a sailor hat

His rise to the top of the business world was not always smooth.

But former Dragons' Den star Duncan Bannatyne ditched the suit and tie in favor of a captain's hat as he celebrated his 75th birthday in Miami with his wife and a group of glamorous friends.

The Scottish entrepreneur, known for his outspoken views on business people on the BBC show, was pictured partying with 43-year-old Nigora Whitehorn last week.

The couple were spotted exploring their surroundings on an electric bike before lunch and then enjoyed a glass of wine at a luxury restaurant.

Bannatyne was said to be in high spirits and appeared to be recovering from a recent injury after he was seen using a walking stick and wearing a knee brace following a luxurious Caribbean holiday.

Earlier on Friday, he celebrated his milestone 75th birthday with a posh lunch while spending quality time with his beloved wife Nigora Whitehorn.
