OpenAI hopes to upend the browser market currently dominated by Google Chrome, but it depends on paid users.

The Competition and Markets Authority says the tech giant dominates the smartphone market along with Google.

Google's president and chief investment officer Ruth Porat tells the BBC there are "profound opportunities in the UK".

Google says the decision misunderstands how its products work, and it will appeal the ruling.

The tech giants both expressed concern at the rulings, but said they will co-operate with investigations.

Robo-taxi services and driverless trucks are gaining ground but progress is painstaking.

The tech giant previously ruled out applications that were "likely to cause harm".
