Why is Europe short of lorry drivers and how bad is the crisis?

Some 400,000 more lorry drivers are needed to plug a shortfall across Europe, according to consultancy Transport Intelligence.

The same estimates suggest that Poland needs at least 120,000 drivers, while Germany and France also have a shortage of more than 40,000 each.

The industry estimates that the UK needs 100,000 drivers to partly alleviate supply chain pressures that have seen people queueing at petrol stations around the country this week.
