2021 elections: Everything you need to know about the Scottish, Welsh and local elections

Adults in England, Wales and Scotland will be voting on Thursday 6 May

Elections will be held across England, Scotland and Wales on Thursday 6 May.

About 48 million people can vote, to elect about 5,000 candidates to positions of power.

It's a little bit complicated as there are several different types of elections happening at once.

Here's everything you need to know.

Scotland and Wales parliamentary elections

Members of two of the UK's parliaments - Holyrood in Scotland and the Senedd in Wales - will be chosen by voters in those nations.

These parliaments are responsible for areas like health, housing and education.

The powers were moved away from the UK Parliament in London under a process called devolution.

To vote in the Holyrood and Senedd elections you must be 16 or over on the day of the election.

Voters in other elections must be over 18.

Why do these elections matter?

Independence is expected to play a big part in the Scottish elections as the country's largest political party, the Scottish National Party (SNP), wants the country to split from the UK and be in charge of itself.

If the SNP gets more votes this time around they will have more power to potentially get another vote for independence on the table.

In Wales, Labour has been in power since 1999 but faces a challenge from the Conservatives, with other parties also seeking to gain seats.

The campaign has seen proposals on income tax, social care, climate change, Welsh independence and a proposal to abolish the Welsh parliament altogether.

Local elections in England

Bin collection and recycling services are run by local councils

Across England thousands of local council seats will also be up for grabs.

Local elections give adults the chance to choose who represents them in their towns and councils - basically, at a more local level.

There are several different types of local elections in the UK. That's because the way your local council is organised depends on where you live. Read this to find out more about local elections.

Some places in the UK have just one group of councillors who run all sorts of local services. In other areas, responsibilities are split between two or more 'layers' of councillors.

Local councillors are in charge of issues like bin collections, public transport, local education and environmental issues in the area.

A major survey suggests Covid-19 will be the most important issue to people as they cast their vote in the upcoming local elections.

London

Councillors can affect local services like the fire brigade

Londoners will elect 25 members of the London Assembly - and a mayor.

The London mayor's powers include: setting bus and tube fares and deciding targets for the number of affordable homes.

London Assembly Members examine the mayor's decisions.

Mayors

There will be also be elections to choose 12 mayors in different regions and cities across England.

Police and crime commissioners

There will be elections in England and Wales for police and crime commissioners.

They set the budget and priorities for police in their area.

MPs

There will also be a by-election to pick who represents Hartlepool in the Westminster Parliament after the previous Member of Parliament (MP) resigned.

A by-election is a one-off election that happens in between general elections, usually when an MP in a certain area has died or resigned.

People are interested about what happens here as Hartlepool has been held by a Labour MP for more than 50 years, so if this changes it could give an indication of whether voters in traditional northern Labour areas are still turning to the Conservatives as they did in the last general election.

How are the winners chosen?

This is where things get even more complicated as there are different rules on how votes are cast for different elections.

Scotland, Wales and London Assembly

• People have two votes - one to choose who represents the constituency (area), and one to choose which party represents their wider region.

Mayors and police and crime commissioners

• Voters select a first and second choice - if no candidate receives 50 percent of first-preference choices, the top two go into a run-off.

• If voters' first candidates have been eliminated then their second preferences are taken into account.

English councils

• Voters have one vote for each available seat in their area.

• In most cases, that means one vote - but large wards may have multiple seats.

• Whoever receives the most votes wins the seat.

• If one party wins more than half the council seats, they have control of the council.

• If no party has a majority, parties will often join forces (known as a coalition).

When will we know the results?

Whenever adults go to the polls to vote in elections - whether local or general - many people often take their dogs and snap funny photos like this one!

Covid safety measures will be in place at counting venues.

That means counting votes is expected to take longer than usual and could go into the weekend.
