Left-wing think tank urges Andy Burnham to rejoin the EU as he prepares to unveil Brexit options in Brussels

The IPPR report declares that 'the world Britain built its post-Brexit strategy for no longer exists', according to executive director Harry Quilter-Pinner. It says Britain lacks the 'scale' to face 'Russian aggression, American unreliability and Chinese coercion' alone. Prime Minister Andy Burnham will set out options at the UK-EU summit on November 20, with rejoining likely among them. Kemi Badenoch warned his push risks 'unpicking' Brexit.

IPPR's Laura Chappell: 'We can't take back control while being an outsider in Europe.'

The report dismisses the Government's balancing act between the US and Europe as 'a strategy for survival'.

Sadiq Khan is leading calls to rejoin, backed by London MPs.
