Coronavirus lockdown in the UK: Here's a guide to what you can (and can't) do

Alan McGuinness, political reporter

Boris Johnson has announced a series of wide-ranging measures to tackle the UK's coronavirus outbreak.

The headline from Mr Johnson's address to the nation is simple.

Britons must stay at home and only leave the house under a small number of circumstances in order to help in the fight against COVID-19, the disease caused by the coronavirus.

So when can I leave the house?

Effective immediately, the government says you can go outside only for "very limited purposes":

"These four reasons are exceptions," the government's latest guidance says.

"Even when doing these activities, you should be minimising time spent outside of the home and ensuring you are 2m (6.5ft) apart from anyone outside of your household."

If you work in what the government has deemed a "critical sector", or your child has been identified as vulnerable, you can still take your children to school.

What about seeing friends and family?

If your friends ask to meet you, you should say no.

You should also not be meeting members of your family who do not live in your home.

What else did the PM announce?

All shops selling "non-essential" goods will be closed, as will a range of public spaces and venues.

This covers:

Public gatherings of more than two people are also banned.

There are two exceptions to this, according to the government's guidance:

All social events, including weddings, baptisms and other ceremonies, are also banned - but funerals can go ahead with immediate members of family in attendance.

Parks will stay open for exercise, but gatherings there will be dispersed.

How will the government enforce this?

Police will have powers to disperse gatherings, while anyone who is found not to be following the rules could be fined.

How long will these restrictions last for?

The PM said the restrictions will be "kept under constant review" and last for a minimum of three weeks.

At that point, the government will examine the evidence and see if they can be relaxed.
