BT could be broken up amid concerns that it is not fit to deliver the next generation of super-fast broadband under plans being considered by ministers.

The Government is considering whether BT should be forced to sell off its broadband division amid concerns over its performance, which has been criticised as “dire” by Tory MPs.

It comes after Karen Bradley, the Culture Secretary, announced plans to give people a legal right to request access to minimum broadband speeds despite opposition by BT.

The new review represents a significant blow for BT, which believed it had seen off the threat of being broken up last year.
