Jeremy Corbyn has argued that Labour must reject full single market membership if his hard-Left socialist vision is to become a reality as his supporters were accused of using underhand tactics to quash opposition.

The Labour leader told the party’s Scottish conference that the UK’s post-Brexit relationship with the EU must be “fully compatible” with his radical agenda, including nationalising the railways and stopping employers “importing” cheap labour.

He used his keynote speech to the Dundee gathering to argue that Labour could not accept a Norway-style deal for membership that would leave Britain “as a passive recipient of rules decided elsewhere by others".

But Catherine Stihler, a Scottish Labour MEP, rejected his claims and argued there was “no Left-wing case” for leaving the single market. In a pointed dig at Mr Corbyn, she argued it was Labour’s job “to challenge anti-immigrant sentiment".

The Labour leader was also forced to deny that he had tried to nullify dissent on single market membership after it emerged the conference is highly unlikely to get a vote on the key issue following a debate on Sunday.

The party’s national executive, which is dominated by his supporters, presented a “unity” motion for debate that contained no mention of the single market. Unless this is defeated, which is highly unlikely, there is no prospect of a vote on the issue.
