>> Revving up their defense in the battle against the regulators. Uber launching a legal challenge against new rules in London requiring private hire drivers to pass written English tests. Authorities had already announced this in January, following months of demonstrations by the capitol's famous black cabs. But Reuters UK correspondent, Costas Pitas says, the devil is in the detail.
>> One of the things that they said they would do, are introduce English language tests. But the detail of what they will do has only come out in the last few weeks. For example, they say there should be writing and reading skills in those English language tests. They've also said that companies like Uber need to have a London call center, that drivers need to have insurance for private hire even when they're not using the vehicles for private hire purposes.
>> A new London call center would need to be set up by the first of October. Uber says that's way to soon. But transport for London says it's not budging on the proposals, and that could put thousands of drivers at risk of losing their jobs. Well, quite a large number of Uber drivers don't have English as a first language, so they would be required to pass this test.
Uber say, it costs about 200 pounds, and they say that the test is more stringent than taking the UK citizenship test, which also has a language element to it. So essentially, Uber is concerned that some of its drivers, and those drivers would presumably be concerned too, may not pass the test.
>> For tech startups like Uber and Deliveroo, navigating regulation and opposition from unions is becoming increasingly problematic. Earlier this week, food delivery firm Deliveroo was forced to backtrack on a new contract for its workers after weeks of protests. Uber will be hoping it's more successful at steering its way through any new rules.
