Which Dragon's Den investor joined the British programme in series 13 in 2015?

Touker Suleyman joined the British Dragon's Den investment panel in series 13 in 2015.

Suleyman is a British-Turkish-Cypriot entrepreneur and investor known especially for businesses in fashion, retail and manufacturing. His entrepreneurial career began in textiles, and he later became associated with the fashion brand Hawes & Curtis and other commercial ventures.

His arrival came during a period when Dragon's Den was refreshing its panel of investors. Each dragon brings a different commercial background, so the programme's negotiations can turn on whether a pitch needs retail distribution, manufacturing expertise, branding help or general capital.

A common error is confusing Suleyman's debut with those of later dragons such as Tej Lalvani and Steven Bartlett. Series 13 is the relevant production number, and the year associated with his joining is 2015.
