Billionaire, philanthropist and Phones 4u founder, John Caudwell, went head-to-head with Labour's shadow chancellor, John McDonnell, after the politician extended an invitation for tea.

Mr McDonnell had previously stated that "nobody needs or deserves" to be a billionaire - which Mr Caudwell said was creating a "divisive message".

The businessman also said that nearly every wealthy person, including him, was thinking of leaving the UK if Labour win the election.
