At the moment, ministers say there is nothing in the current data to suggest that England can't move into step four of the roadmap on 21 June.
But what does the roadmap actually commit to?
It says the government will reopen venues like nightclubs, it hopes to lift caps on numbers at weddings and remove "all legal limits on social contact".
If you look at the rest of the roadmap, it's pretty clear that "social contact" has been used to refer to how many people can gather and where.
So what it doesn't commit to is ending measures such as the one metre plus rule in pubs and restaurants, wearing face masks or even working from home. Those measures are being looked at by a government review.
The results had been expected to be announced at the end of May but are now likely to come with the decision on step four on 14 June.
That raises the possibility of step four going ahead as planned - but with at least some social distancing measures staying in place.
In fact, the original roadmap says that "some measures may be required even after all adults have been offered a vaccine".
The date for that is still currently 31 July.
So even if step four does go ahead on 21 June, we shouldn't expect a return to normal overnight.
