Where are the battlegrounds in Wales?
By Adrian Browne, BBC Wales political reporter
Labour, which has been in charge in Wales since devolution 22 years ago, has been campaigning hard in seats it lost to the Conservatives at the 2019 general election.
For their part, the Tories have been putting in the hours to try to convert those Westminster gains they made into Senedd victories.
Wrexham, Vale of Clwyd, Clwyd South and Delyn turned from red to blue in 2019, and it is no surprise both parties have focused much of their attention on these seats this time around.
In the south, the Conservatives have hopes of ousting Labour in the Vale of Glamorgan, a seat the Tories have held at Westminster since 2010.
Labour is also keen to win back the Rhondda seat captured by Plaid Cymru at the 2016 poll.
As well as hoping to prevent that seat from returning to the Labour fold, Plaid is targeting the Labour marginal of Llanelli, which has flipped between the two parties since the dawn of devolution in 1999.
Tory-held Aberconwy is also a Plaid Cymru target seat, and the party has also used its campaign to urge voters to chose Plaid in their second vote, with the aim of picking up extra members in the regional seats.
The Liberal Democrats are concentrating on keeping their one remaining seat, Brecon and Radnorshire, with the possibility of picking up a regional list seat as compensation if they fail to do so.
Meanwhile, Abolish the Welsh Assembly, Reform UK, and the Green Party are hoping to make a breakthrough in those regional votes.
UKIP won seven regional seats in 2016, shortly before Wales and the UK voted to leave the EU in a referendum.
It will be hoping to, at the very least, retain a presence in Cardiff Bay.
Welsh campaigning focus on the key seats
The leaders of the biggest parties in Wales will be out campaigning in key seats in north, south and mid Wales.
Labour's Mark Drakeford is heading to the Vale of Glamorgan, while the Tories' Andrew RT Davies will be in the north of the country.
Plaid Cymru's Adam Price will focus on Llanelli while the Welsh Lib Dems' Jane Dodds will be in Brecon.

What's up for grabs in Thursday's elections
A total of around 48 million people across England, Scotland and Wales will be able to vote in this week's bumper crop of elections. Here is a rundown of what is up for grabs on Thursday:
Zahawi: Planning underway for vaccine booster jabs
Vaccines minister Nadhim Zahawi has been doing interviews this morning.
He answered lots of questions about the vaccine roll-out programme and said will be an update “later this week” on international travel.
He was asked about reports that over 50s may receive a third booster vaccines before the winter.
He said Professor Chris Whitty and other UK chief medical officers are looking at the "durability and protection of the current vaccines".
"We want to give the scientists as many options available, to deploy a booster", he said.
He added that work was also being carried out to find which additional shot would deliver the greatest protection:
Reynolds: People 'might not be totally convinced yet' about Labour
The shadow work and pensions secretary, Jonathan Reynolds, has been doing the morning round of interviews for Labour.
He was asked on Radio 4's Today programme if polling suggesting Labour could be in trouble in the Hartlepool by-election meant the party was going backwards.
Mr Reynolds said polls are not always correct and turn out would be important:
Scotland's party leaders final pitch for votes
The leaders of Scotland's biggest political parties made their final pitch to the nation last night in a BBC TV debate.
They debated a range of devolved issues, the coronavirus pandemic and the merits of another independence referendum.
The SNP leader Nicola Sturgeon ruled out a non-lawful referendum, while the leader of the Scottish Conservatives Douglas Ross faced questions over how Scots could secure another vote if they want one.
Here are our top five takeaways from the debate.
Davey: A weird campaign but party cutting through
The Lib Dem leader, Sir Ed Davey, has also been on BBC Breakfast this morning.
He said it has been a "weird campaign" due to the pandemic and limitations on doorstep campaigning earlier in the year, but his party is cutting through because they are "community politicians who get things done".
People have really reconnected with their community during the pandemic, he said, and the environment is a priority.
Sir Ed said the easing of restrictions on doorstep campaigning had helped his party get their message across:

Bartley: Greens want to build a well-being economy
The co-leader of the Green Party, Jonathan Bartley, has been on BBC Breakfast this morning.
He said his party's message is very simple - if you want green, vote Green.
The pandemic has made the environment a key concern for voters, he said, and not just in terms of dealing with the climate and ecological emergency but improving local communities.
Mr Bartley said the Greens have policies that stretch across every sector of society:

No standard election - no handshakes, no kissing babies
Adam Fleming
Chief political correspondent
We'll get some standard campaigning from the party leaders today, but it's not really been a standard election campaign.
These are such a strange times for all of us, no shaking hands and certainly no kissing any babies.
The coronavirus pandemic has meant a higher number of postal votes, but tomorrow people will go to their polling stations and cast their vote – socially distanced, of course.
To understand what could happen in England, is to look at whether the Conservatives can consolidate their hold on places that they won from Labour at the last general election in 2019, or whether Labour can start to stage a bit of a fight back.
This election has become a bit of a test for Keir Starmer and how his first year as Labour leader has gone.
Will they hold on to Hartlepool in the by-election there?
We'll probably get the result around about four o'clock on Friday morning, and then we'll get results from all those many, many contests, through Friday, Saturday, Sunday, and maybe even Monday
The Liberal Democrats, and the Greens tend to do quite well in local elections, certainly much better than they do at Westminster election so watch out for them as well.
But the big issue that is going to dominate is the result in Scotland.
If there is a majority in favour of another independence referendum, that will start a massive row between Edinburgh and London, about whether to have one.
It’s Boris Johnson who has the power to grant it or not, and the debate could dominate our politics for months, and maybe even years.
