Barclays Local Business, who compiled the figures, suggests that 44 per cent of today’s business leaders were the dreamers of yesterday.

Commenting on the figures, John Davis, marketing director for Barclays Local Business says: ‘This survey highlights what many bosses have probably suspected for a long time – that for some employees, their current job is the last thing on their mind when they are at work.

‘For budding entrepreneurs, the routine of their job can spark dreams of going onto bigger and better things.’

However, it was not just the workplace where potential entrepreneurs could think about their future. Around eight per cent mull over a potential new venture while on holiday and a further six per cent think about being their own boss between pints in the pub.
