I fear we're heading for lifting. Personally I tend to go for the act in haste... approach, and I'd be a lot happier with another three weeks, as it'd allow us to see how other places were coping - bear in mind there's a lag in getting the data.
Not only that, but some places are easing off from a stricter base. Pipkin's being allowed out on a walk, but we've never been stopped from doing that.
A clear strategy would, IMHO, articulate that we're giving it three weeks as-is, and here are the plans afterwards... *as long as the data follows the path as predicted*. If it doesn't, lockdown will be extended. Persuade people it's in their interests to follow the rules for just a bit longer, as it's better for them in the long run.
