Three things that could derail Boris Johnson's timetable for easing lockdown

mirror.co.uk:

Boris Johnson has said he is "very optimistic" that England can finally return to normal life on June 21 under his four-step roadmap out of lockdown.

However the Prime Minister warned that "nothing can be guaranteed", as the Government maintains a cautious approach to freeing Brits from the limits governing daily life.

Plans to reopen schools and allow greater outdoor socialising in March, to reopen beer gardens, shops and salons in April, and to scrap most rules on social contact in May have offered hope to millions.

However the PM has been clear that he will be governed by "data not dates" and the timetable could slip if the virus begins to spiral.
