Lockdown easing 'supremely difficult' - PMpublished at 15:52 British Summer Time 11 May 2020
Boris Johnson tells MPs that the reopening of society and the UK economy should go ahead with "utmost caution".
He says the R rate - which measures the spread of infection - has fallen from between 2.6 and 2.8 in April to between 0.5 and 0.9 now.
The prime minister says making sure the disease does not spread while reopening the economy will be a "supremely difficult balance to strike".
He adds that some parts of the UK may need to stay in "full lockdown" longer than others - but this should be short-term.
