A free "robot lawyer" that has overturned thousands of parking tickets in the UK can now fight rogue landlords, speeding tickets and harassment at work.

Joshua Browder, the 20-year-old British student who created the aide, has upgraded the robot's abilities so it can fight legal disputes in 1,000 different areas. These include fighting landlords over security deposits and house repairs, and helping people report fraud to their credit card agency.

"There’s so much exploitation going on where landlords aren't behaving properly. I’m really excited about how it can help people," said Browder. "I'm not a lawyer by training, I just like building exciting products and training them. I don't think there's been enough innovation in consumer law.

He added: "I really hope it will help people stand up for their rights for free and instantly."
