London Tech Week is one of the key moments in the UK tech calendar. Centred around the Queen Elizabeth II conference centre, 500 events are held at venues around the capital, attracting more than 30,000 visitors.
Many entrepreneurs have been eager to do an interview with perky event co-hosts Oli Barrett and Sonya Barlow as they and their camera teams take interviewees outside – problems with the venue’s air conditioning system have meant attendees have sweltered in the unseasonably warm weather, with reports of some people fainting on exhibitor stands while trying to sell their startups.
