Many of today's jobs are at high risk of being automated in the next two decades, according to researchers.

Oxford University and accountancy firm Deloitte warn that just over a third of jobs could be lost as automation increases and they say the worst hit will be low-skilled, low-paid workers who are five times more likely to be replaced by machines.

Some skills which computers cannot replicate will become increasingly valuable in the employment market.
