Everything you need to know about the coronavirus lockdown

Boris Johnson has put the country into a three-week lockdown to prevent further spread of coronavirus.

Here's what you can and can't do under the new guidance:

People will only be allowed to leave the house for limited purposes

Mr. Johnson said that residents will only be allowed to leave their homes for shopping for basic necessities - as infrequently as possible.

One form of exercise a day will be allowed - for example a run, walk or cycle - alone or with members of your household.

You will be able to leave the house for any medical need, or to provide care or to help a vulnerable person.

Travelling to and from work will be permitted, but only when absolutely necessary and work cannot be done from home.

All shops selling non-essential goods are to shut

To ensure compliance with the instruction to stay at home, Mr Johnson said all shops selling non-essential goods, including clothing and electronic stores, will be closed.

Libraries, playgrounds, outdoor gyms and places of worship will also be closed.

Hotels, hostels, bed and breakfasts, campsites, caravan parks, and boarding houses for commercial or leisure use will also be closed.

What shops will remain open?

Supermarkets and other food shops, healthshops, pharmacies including nondispensing pharmacies, petrol stations, bicycle shops, home and hardware shops.

Other stores which can remain open include laundrettes and dry cleaners, bicycle shops, garages, car rentals, pet shops, cornershops, newsagents, post offices, and banks.

Cafes and restaurants which do takeaway or delivery, along with market stalls which offer essential retail, such as grocery and food

All gatherings and social events will be stopped

Gatherings with more than two people in public, excluding people you live with, will be stopped, as will weddings, baptisms and other ceremonies.

Mr Johnson said these measures exclude funerals, but only immediate family will be able to attend.

What happens if I don't follow the rules?

Anyone who is not following the rules could be fined, Mr. Johnson said, while police will have powers to disperse gatherings.

Although parks will remain open for exercise, gatherings will be dispersed.

Could the lockdown be extended beyond three weeks? Mr. Johnson assured the public that the restrictions are to be kept under constant review.

They could be relaxed in three weeks - on Easter Monday at the earliest - if evidence shows the government is able to.
