Britain will rejoin the EU in the future, Tony Blair has predicted – as polls show support for rejoining climbing ever higher.

The former prime minister told the New Statesman magazine that a “future generation” would take the UK back inside the bloc and reverse Brexit.

A new survey by Deltapoll carried out between 14-17 July found 56 per cent of people would vote to rejoin the EU versus 38 per cent who would vote to stay out.

“I believe at some point a future generation will take Britain back into Europe, and, you know, you just have to look at what’s happened,” he told the magazine in a wide-ranging interview.

Sir Tony went on to describe Brexit as “a constant sadness to me”.

Labour has ditched its anti-Brexit stance under Keir Starmer, ruling out rejoining the bloc or even its single market.

Elsewhere in his interview Sir Tony warned that the only way of fighting climate change was to cooperate with China.

He said the climate was the “single biggest global challenge” but that Britain’s emissions were dwarfed by that of larger countries.

“Don’t ask us to do a huge amount when frankly whatever we do in Britain is not really going to impact climate change," he told the magazine.
