Uber launches in Glasgow today, making it the first city in Scotland to have access to the controversial taxi service. The company is planning to launch in several more Scottish cities—which will include the capital Edinburgh—over the next 12 months.

According to The Scotsman, hundreds of drivers are believed to have already signed up to work for the company, with 20,000 people Glasgow having already downloaded the app, making it Uber's biggest UK launch. The service was originally supposed to launch in Edinburgh, but the company recently admitted that it "struggled" to find the right staff to man the service, delaying its launch.

"We are super excited about this," Max Lines, general manager for Uber Glasgow told The Scotsman. "It is the first city to launch in Scotland and is our biggest UK launch to date. I would love to launch in Edinburgh soon, but I am not exactly sure when it will be. We still need to do a bit of preparation, but if we could do it in the next two months, that would be great."

Uber’s UK division is already operating in several large cities including London, Birmingham, and Leeds. Notably, Uber only operates its UberX service in the UK, which requires drivers to be professionally licensed. Its unlicensed UberPOP service—which allows anyone with a car to become an Uber driver—has come under fire in several countries, most recently in Brussels, where a court ruling ordered it shut down.

Uber has had a hard time setting up shop in Europe, facing protests from licensed taxi drivers. Two days of violent protests took place in France earlier this year, ending with the French authorities taking two Uber executives into custody for questioning as part of an investigation into UberPop.

In recent news, two women in the US are suing Uber, alleging that they were victimised by their Uber drivers, and that the company doesn't do enough to ensure rider safety.
