Nine million people in London are set to face tougher coronavirus restrictions banning households mixing indoors - including in pubs - from 0.01am on Saturday.
And London is not the only area which will be hit with the Government's second-harshest lockdown level at midnight tomorrow.
Residents in Essex, Elmbridge, Barrow-in-Furness, York, North East Derbyshire, Chesterfield and Erewash will also have the new restrictions imposed on them.
Tier 2 rules includes a ban on meeting socially with friends and family indoors and weddings will be limited to 15 and funerals to 30.
Gyms, shops, schools, universities and churches will stay open.

Here, MailOnline looks at what it will mean for all regions under Tier 2 lockdown from Saturday:
Can I still go to my friends' house tonight or tomorrow night?
Yes. Tomorrow will be the last day when you can visit a friend's house for now, but you must ensure no more than six people gather - and you leave before midnight.
Can I have my friends over from Saturday?
No. People must not meet with anybody outside their household or support bubble in any indoor setting, whether at home or in a public place.
Can I see my friends inside a pub or a restaurant?
No. You must not meet socially with friends and family indoors in any setting unless you live with them or have formed a support bubble with them.
This includes private homes, and any other indoor venues such as pubs and restaurants.
Can I meet my friends in a pub garden?
Yes. You can gather in groups of six outside at venues which are following Covid-secure guidance, including pubs, restaurants, shops, leisure and entertainment venues and places of worship.
At least one person in the group should give their contact details to the venue or check in using the official NHS Covid-19 app so NHS Test and Trace can contact you if needed.

Can I see friends outside?
Yes. You may continue to see friends and family you do not live with (or have not formed a support bubble with) outside, including in a garden or other outdoor space.
When you do so, you must not meet in a group of more than six.
Do children count in the 'rule of six' outdoors?
Yes. This limit of six for meeting people outdoors includes children of any age.
Can I still meet inside with people from my support bubble?
Yes. You will still count as one household who can meet together indoors or outdoors.
A support bubble is where a household with one adult joins with another household.
Households in that support bubble can still visit each other, stay overnight, and visit public places together.
Informal childcare can also be provided via childcare bubbles (see below).
Is the support bubble affected by London changing tier?
No. Your support bubble is still valid despite London going into a higher tier, so you can continue to function as one household.
Can my friends visit if they are from outside London?
No. If you live in a 'tier two' area you also cannot meet indoors with people from outside of the area, unless exceptions apply (see final question below).
Can I go to stay at a hotel or Airbnb home within London?
Yes. You can still travel within high alert level areas to hotels and other guest accommodation, but you should only do this with people in your household or support bubble.
You can only stay in a private home - which includes self-catered accommodation such as holiday cottages, apartments or boats - with members of your own household or support bubble.
You can stay in a hotel or similar accommodation (for example, a hostel or bed and breakfast) with another household.
However you should avoid sharing rooms with people you do not live with or otherwise socialising indoors, for example in each other's rooms, in reception areas, or in restaurants and bars.
Can I still go on holiday outside London?
Yes, with exceptions. You can still go on holiday outside of high alert level areas, but you must only do this with people in your household or support bubble.
Can I still go on holiday to Wales?
Probably not. Welsh First Minister Mark Drakeford is proposing a travel ban on visits to Wales by people living in areas of England, Scotland and Northern Ireland with high levels of Covid-19 from Friday.
He said police in Wales could use number plate technology to catch people from UK coronavirus hotspots who illegally enter the country.
Can I still go on holiday to a tier three area like Liverpool?
No. You should avoid travelling to any part of the country subject to very high local Covid alert levels.
Can I still move home or look at a house in London?
Yes. You can still move home. Estate and letting agents and removals firms can also continue to work and people looking to move home can continue to undertake viewings.
Do I have to end my current holiday outside London if it's with another household?
No. At the time that the new local restrictions are brought in, if you are currently on holiday with another household outside London, but are from London, and are staying in a private home and it is not reasonable for you to curtail your stay, you should finish your holiday as planned.
The Government advises that until the end of this holiday you should 'make every effort to reduce socialising indoors outside of your household and follow local regulations and guidance'.
Can I still use public transport?
Yes, but with restrictions. The Government says you may continue to travel to venues or amenities which are open, for work, voluntary, charitable or youth services, or to access education, but you should 'aim to reduce the number of journeys you make where possible'.
If you need to travel, the Government encourages people to walk or cycle where possible, or to plan ahead and avoid busy times and routes on public transport. This will allow you to practise social distancing while you travel.

Do the tier two rules follow me if I travel outside my area?
Yes. The rules are based on the highest tier level out of a) where you live and b) where you are visiting.
Therefore, if you live in London, you must abide by London's rules wherever you go.
But if you are from a tier one area and are visiting London, you must abide by the rules for London.
Can I visit my parents in an area outside of London?
Yes. However you must follow the rules applying to where you live, so you would have to meet them outside and ensure there is not a group of more than six people.
Can I still commute into London if I live in a tier one region outside the capital?
Yes. The Government says people can continue to travel into a high alert area for work, but should 'aim to reduce the number of journeys you make where possible'.
Are the exceptions to the rule of six for children?
Yes. There are exceptions from legal gatherings limits for registered childcare, education or training, and supervised activities provided for children, including wraparound care, youth groups and activities, and children's playgroups.
This means you can continue to use early years and childcare settings, including childminders, after-school clubs and nannies.
Who can provide childcare support in private homes and gardens?
Registered childcare providers including nannies, people in your support bubble or people in your childcare bubble.
What is the definition of a childcare bubble?
A childcare bubble is where someone in one household provides informal (unpaid and unregistered) childcare to a child aged 13 or under in another household.
For any given childcare bubble, this must always be between the same two households.
Friends or family who do not live with you and are not part of a support or childcare bubble must not visit your home to help with childcare.
Childcare bubbles are to be used to provide childcare only, and not for the purposes of different households mixing where they are otherwise not allowed to do so.

No. The Government's definition of a household is one person living alone, or a group of people (not necessarily related) living at the same address who share cooking facilities and share a living room, sitting room or dining area.
A household can consist of a single family, more than one family or no families in the case of a group of unrelated people.
