A new era has begun for the United Kingdom after it completed its formal separation from the European Union. The UK stopped following EU rules, as replacement arrangements for travel, trade, immigration and security co-operation came into force. On today's programme, we'll hear how we got to this point with Marie Keyworth, and then Vivienne Nunis will tell us what's happening today. Then, Dr Anna Jerzewska, Director of the trade consultancy Trade and Borders and Allie Renison with the Institute of Directors will discuss the UK's trade opportunities in the future.Producer: Frey Lindsay.(Picture credit: Reuters.)
