Rishi Sunak is set to announce the northern leg of HS2 will be scrapped due to spiralling costs.

The news comes afterThe Independent revealed the prime minister and chancellor, Jeremy Hunt, held secret talks about whether to shelve parts of the high-speed rail on 13 September.

The Independent understands that the route north of Birmingham will be delayed for seven years in a bid to abandon the project in the long term – a move that has sparked fury among northern mayors and business executives.

A source close to government discussions said the Prime Minister was most likely to make the announcement in his speech at the Tory party conference on Wednesday, though it could now be brought forward to Tuesday.

Rishi Sunak has refused to confirm The Independent’s findings, despite admitting “It’s clear that the costs of this programme have escalated far beyond what anyone thought at the beginning,”
