Hampshire-based businessman Stephen Voller hopes the Dragons won't put the brakes on his new electric car invention, as he smashes the Den record for the most money ever asked for.

Serial inventor Michael Pritchard hopes to clean up in the Den with his revolutionary invention that allows every last drop of liquid to be used in household product sprays. Young Bolton entrepreneurs Umar Mohammed and Ahmed Suleman hope they'll get investment from a Dragon with their fast food curry trays.
