Cambridge-based chip designer’s owner prefers US to London but PM and chancellor aim to revive talks

Liz Truss and Kwasi Kwarteng are preparing a fresh attempt to persuade Japan’s SoftBank to list Cambridge-based chip designer Arm in the UK.

The prime minister and chancellor are hoping to revive talks with SoftBank, which reportedly halted plans to explore a London listing after the political upheaval as Boris Johnson resigned.
