Chamali Fernando, 35, was adopted by party members to fight the 2015 poll at a special general meeting.
Ms Fernando, who is of Sri Lankan ancestry, said: “I am delighted to be provided the opportunity to champion issues that matter to the people of Cambridge whilst ensuring politics becomes more relevant, welcoming and representative of society. The plan I will set out to achieve success for households, businesses and organisations of Cambridge is ambitious, bold and different.”
Ms Fernando is a senior policy advisor to the campaign fighting for the creation of an international court for the environment, and as a barrister has dealt with people trafficking and honour killing cases.
Ms Fernando, who studied A-level politics in Cambridge and has campaigned for the Conservatives locally, said it would be “an honour” to serve as the city’s MP.
She added: “Few cities in the world have the wealth of knowledge, expertise and dynamism that we are fortunate to hold at our fingertips. There are two great universities which demonstrate our potential – one is a national treasure and the other, a gateway to learning in an ever-changing global economy.”
