Brexit has made supply chain "bottlenecks" worse in the UK, according to the independent financial watchdog that provides the government with data.

Greggs Plc said on Wednesday the U.K. bakery and fast food chain has become the latest food business to be hit by supply chain interruptions that are impacting businesses across the retail and hospitality sector in Britain.

Many European drivers have left the country, Tesco chief explains.

Britain is facing a shortage of Greggs vegan sausage rolls after it became the latest food product to suffer from supply chain disruption.
