Dragon's Den star Duncan Bannatyne marries fiancée Nigora Whitehorn at beachside ceremony in Portugal

Duncan Bannatyne has tied the knot with fiancée Nigora Whitehorn at a stunning beachside ceremony in Portugal.

The Dragon's Den star, 68, wore a classic tartan kilt and jacket for his walk down the aisle, whilst Nigora, who is originally from Uzbekistan, chose a long strapless white dress with a lace bodice and co-ordinating veil for the big day.

Friends and family have shared a number of pictures from the occasion, which show the couple celebrating with the assembled guests.

In addition to Saturday's ceremony, the pair also had an Uzbek party on the following Sunday, with Duncan tweeting before the weekend began: 'Our large families arriving in Portugal today, getting married Saturday, Uzbek party Sunday, UK Election Wed. What an exciting week. 😎'

The wedding is the third for Duncan, who has four daughters by first wife Gail, whom he married in 1983, and a son and a daughter with second wife Joanne, whom he split from in 2010.

Duncan and Nigora met in 2014, and the father-of-six popped the question two years later during a holiday to Monaco, presenting his future bride with a pear-shaped diamond ring.

During an interview with the Daily Mail in 2015, Nigora said of her husband-to-be: 'I absolutely adore [him]. He is the most softest, amazing, kind person. My words are not going to be good enough to describe him.'

She also addressed the 30-year age gap in their relationship, adding: 'It really upsets me when people judge me, saying: "Oh, how come someone so young and beautiful all of a sudden is in love with millionaire Duncan Bannatyne?"'

'You fall in love with someone for their personality, for their character, for their charm and charisma. Age is just age. I adore Duncan as a person and I think that’s what deep love is about.'
