Alok Sharma speaks at daily press conference on Covid-19 from Downing Street

The video discusses the UK's transition from COVID-19 Level 4 to Level 3, outlining a three-step plan to ease lockdown measures. Step One allows those unable to work from home to return to work and permits outdoor activities with social distancing. Step Two, starting June 1st, aims to reopen primary schools and non-essential retail, with cultural events held without crowds. Step Three, no earlier than July 4th, plans to reopen more businesses, including leisure facilities and places of worship, with new safety measures. Each step will be monitored to prevent a second peak.
