James said there may be an element of signalling from the Government that further moves from Altice will be examined very carefully. "This move makes clear if it wasn't beforehand that a full takeover - or full control - would be very difficult."
"It is hard to think of a company the laws surrounding takeovers are more directed to than BT. The company does things it cannot talk about for the Government. It's hugely important for the resilience of telecoms networks. Not only is it the biggest, but it does a lot of the underlying systems and connections. And it also offers security services through Global. It probably registers in three different ways for the Government."
