Lord Sugar today hit out at Jeremy Corbyn, claiming that if the Labour leader became Prime Minister 'we should all move to China'.

The Apprentice star and former Labour adviser warned that victory for Marxist throwback Mr Corbyn would 'shut down' business in London.

He warned that Britain would 'just rot' if the hardline Left-wing Labour party ever got close to power.

The comments from the outspoken businessman will fuel fears in the Labour party that it will be punished voters for its economic policies.

Mr Corbyn wants to nationalise industry, control rents and hike taxes on business while his shadow chancellor John McDonnell has pledged to 'ferment the overthrow of capitalism'.

Lord Sugar warned the policies would be disasterous for Britain and would lead to an exodus from the country.

He told the Standard: 'He and his policies would be the thing that shuts the whole thing down.

'If they ever got anywhere near electing him and him being the Prime Minister then I think we should all move to China or somewhere like that and let this place just rot.'

The remarks are particularly damaging because Lord Sugar was given his peerage by Gordon Brown and served as an 'enterprise champion' for the Labour government.

However, he quit the party in May after 18 years, condemning Labour's 'negative' stance on business.

Lord Sugar also mocked Sadiq Khan, Labour's candidate to be London Mayor – a role he was once linked to himself. He likened Mr Corbyn and Mr Khan to 'Batman and Robin'.

He added: 'I don't know the fellow and what he stands for but certainly if you want the market to stop then you've got Batman and Robin in those two. If they ever got into power that would create a lot of problems.'

However, on a visit to Scotland today Mr Corbyn insisted Labour is 'doing great'.

After meeting Scottish Labour leader Kezia Dugdale for talks at Holyrood, he told journalists outside the Scottish Parliament: 'We're doing great, party membership is going up after my first conference as leader and things are going really well.'

He has already insisted there is 'no question' of him treating Scottish Labour as a 'branch office' - an accusation levelled by former leader Johann Lamont against party bosses in London.

Polls suggest the SNP are on track to win a second majority term at Holyrood in the Scottish elections in seven months.
