The dust hasn't quite settled on the 2021 elections, with a handful of English councils yet to declare, but the key trends are clear - follow the latest developments here. Ruling parties performed well. The Conservatives enjoyed success across England, Labour secured power in Wales and the SNP won a historic fourth consecutive Scottish Parliament election.

The SNP's Nicola Sturgeon says it means there can be "no democratic justification" for blocking another independence vote. It is, the first minister argues, "the will of the country". However, Prime Minister Boris Johnson suggests talk of "ripping our country apart" would be "irresponsible and reckless". He's invited the leaders of the devolved nations to a summit on how "Team UK" can recover from the coronavirus pandemic, highlighting the vaccine rollout as an example of the "co-operative spirit" bringing the best out of the four nations.

It's likely to make for a lively edition of The Andrew Marr Show, with Ms Sturgeon appearing alongside the Conservative Cabinet Office Minister Michael Gove, on BBC One from 9am.

Sadiq Khan provided a bright end to a turbulent day for Labour, holding off a stronger-than-anticipated challenge from Conservative Shaun Bailey to retain the London mayoralty. Hours earlier, Labour deputy leader Angela Rayner had been sacked as party chairwoman and campaign coordinator in the wake of poor results in the English local elections. The move did not go down well in all quarters . "I can't support this," tweeted Andy Burnham, who increased his majority when winning a second term as mayor of Greater Manchester.

The mayoral races provided his party's brightest moments in England, with Dan Norris gaining the West of England seat from the Conservatives. But Labour broadly lost out to the Tories, who consolidated their position by adding more than 200 councillors and won control of seven councils in the process. And leader Sir Keir Starmer is expected to reshuffle his front bench in the coming days. We'll have any news of that - plus the latest fallout - on our live page.

The trend for ruling parties to perform well continued in Wales, where Labour retained power by winning half the seats in the Senedd. First Minister Mark Drakeford credited his party's response to the Covid pandemic with helping it to retain power, as he promised his next Welsh government would be "radical" and "ambitious".

The Sunday Telegraph describes a Labour "civil war" in the wake of the elections. It quotes former shadow chancellor John McDonnell calling the sacking of party chairwoman Angela Rayner a "cowardly avoidance of responsibility". Its front-page picture features a waving Scottish First Minister Nicola Sturgeon, who the Mail on Sunday describes as having mocked Boris Johnson for the "supposedly clever manoeuvre" of urging her to join a UK-wide "council of war" to rebuild the nation. Meanwhile, the Sunday Times says the prime minister will promise to "stop the brain drain to cities" by bringing well-paid work to former Labour strongholds in northern England. Read the full review.

Along with declarations on those six English councils, we're expecting results in the elections of four police and crime commissioners (PCCs) in Wales later today. Another 12 PCCs will be elected for England tomorrow. And could another test be looming for the parties? If Labour's Tracey Brabin is elected Mayor of West Yorkshire, she'll vacate the Batley and Spen seat she held with a majority of 3,525 votes over the Conservatives in 2019. We're expecting to find out whether that's the case by teatime today.
