Sky and NBC News are teaming up under joint owner Comcast to launch an international news service with a base in the UK, senior executives have revealed.

The English-speaking channel will be called NBC Sky World News and is set to go live this summer, creating a rival to the BBC World Service and CNN in terms of global news coverage.

The move comes almost 18 months after US cable giant Comcast, which has wholly owned NBC Universal since 2013, spent more than £40bn taking over Sky, including its Sky News division.
