tie-up

The tie-up will see the firms sharing critical technology at a time of slowing global demand for electric cars and increased competition from Chinese rivals.

Uber also has a tie-up with Chinese carmaker BYD, the second-largest EV company after Elon Musk's Tesla.

Vodafone and Three have said the tie-up would lead to an additional investment of £11bn in the UK.

The firms added they would be working with the CMA to secure approval for the tie-up.

It has also agreed a new tie-up with book chain Waterstones, which is set to open in its Oxford Street store in London next month.
