Which investor joined the UK Dragons' Den panel in series 15?

Tej Lalvani joined the UK Dragons' Den panel in series 15.

Lalvani is a British businessman best known as chief executive of Vitabiotics, the health and wellness company founded by his father, Kartar Lalvani. Vitabiotics developed and marketed supplement brands including Wellman, Wellwoman and Pregnacare.

He first appeared as a Dragon in the fifteenth series of the BBC programme. His background gave the panel a perspective rooted in consumer health products, brand development and international distribution. He remained part of the regular lineup before later leaving the show.

The series number matters because Dragons' Den has changed investors repeatedly. Tej Lalvani is therefore different from Nick Jenkins, who joined earlier, and from Sara Davies, who joined later. The wording refers to his first series as a panel investor, not to the year in which Vitabiotics was founded.
