The Department of Culture, Media and Sport said it would consult on BT’s proposal, adding that, if the offer was accepted, it would be legally binding.
Culture secretary Karen Bradley said: “We warmly welcome BT’s offer and now will look at whether this or a regulatory approach works better for homes and businesses.

It added that it was already well on the way to offering fast services around the country, with 95%…
