On Tuesday, Rayner said 17 of the 18 worst-hit areas were among the most deprived in the UK.

“While Britain was a successful multi-ethnic, multi-faith country, the government had to show it had a plan to address people’s concerns and provide opportunities for everyone to flourish,” she warned.

A read out of the Cabinet meeting said Rayner told colleagues: “Economic insecurity, the rapid pace of de-industrialisation, immigration and the impacts on local communities and public services, technological change and the amount of time people were spending alone online, and declining trust in institutions was having a profound impact on society.”

Rayner said it was “incumbent on the government to acknowledge the real concerns people have and to deliver improvements to people’s lives and their communities,” the readout said.

Sir Keir said the country will never forget the “unimaginable tragedy” of the “horrific” Southport attacks.
