What is a support bubble?
From Saturday, in England, single adults living alone - or single parents with children under 18 - can form an "exclusive" support bubble with one other household.
The second household can be of any size - but nobody who is shielding should join a bubble. People in each bubble can visit each other's homes and go inside.They will not have to stay 2m (6ft) apart and can stay overnight.
How many people can I meet outdoors?
In England, groups of up to six people from different households can gather outside, in parks or private gardens.
In Scotland, two separate households - up to a recommended maximum of eight people - can meet outdoors, ideally travelling no more than five miles. In Wales, any number of people from two different households can meet each other outside. As in Scotland, families should aim to travel no more than five miles. Beauty spots remain closed. In Northern Ireland, groups of up to six people who do not live together can meet outdoors.
What sports can I play now?
People in England can exercise outside with up to five others from different households. In Scotland, people from two households, in groups of up to eight people, can exercise outside.
So having a kickabout with a football in the park is allowed in both countries, as long as people stay 2m (6ft) apart. However, full games with someone from outside your household are still not allowed because of the physical contact involved.
Individual sports permitted in England, with social distancing, include athletics, golf, horse riding and tennis, where doubles is also allowed with someone from outside your household. Tennis, can also be played in Scotland and Northern Ireland - but not yet in Wales. However, golf can be enjoyed everywhere.
Who has to still stay at home?
People with certain underlying health conditions, or who are pregnant or aged over 70, are deemed to be clinically vulnerable. If you are in this category, you are advised to stay at home as much as possible. Another group, of about 2.5 million people, is categorised as clinically extremely vulnerable.This group had been strongly advised to stay at home at all times and avoid face-to-face contact - so called "shielding".
Now those people in England and Wales are being told they can spend some time outdoors again - either with members of their household, or by meeting someone else at a social distance.
