Theatre hopes to re-open in spring '); '); THE managing and artistic director of the Mill at Sonning is hoping the theatre can re-open at the end of March, subject to coronavirus restrictions. The riverside venue was forced to close when the Government introduced tier 4 rules last month to halt the spread of covid-19. It will remain shut while the third national lockdown, which was introduced this week, stays in place. Sally Hughes has rescheduled all the January and February shows to run throughout late March, April and May. She said: “As I was moving shows around the calendar I had the news on in the background. Amid all the doom and gloom was that wonderful ray of hope. The Oxford AstraZeneca vaccine.
