Social Democratic and Labour Party (SDLP) leader Colum Eastwood has cast his ballot this morning at a primary school in Londonderry in Northern Ireland.
Plaid Cymru leader Rhun ap Iorwerth voted a little earlier this morning. Here he is pictured here coming out of the polling station in north Wales.
Scottish Conservative leader Douglas Ross has also voted this morning. He was pictured with his family at a polling station in north-east Scotland.
And here's Lib Dem leader Sir Ed Davey and his wife Emily arriving to cast their votes in south-west London.
Most of the party leaders seem to have got the job done before midday. We've just had pictures of Green Party co-leader Carla Denyer, going to her polling station the west of England.
No sign yet of parrots or iguanas (see our post at 08:05) but there are dogs galore at polling stations.
Thanks to our readers for sending the below pictures of their furry friends.
And bonus points to anyone who sends us a picture of a pet at a polling station that isn't a dog.

A replacement voting pack can still be issued by your local council's returning officer, external. The deadline is 17:00 BST.
Contact your council's electoral services team, external as soon as possible - replacement packs won’t be available at polling stations.
For your vote to be counted, you can hand in your completed form to your polling station before 22:00 BST. Or you can take it to the address on your postal voting pack today before 1700.
You don't need ID, but you must sign a form.
You can also drop off up to five completed postal vote packs for friends and family.
Political candidates and party campaigners are only allowed to handle postal votes for close family members, or someone they regularly care for.
In certain circumstances, voters in England, Scotland and Wales can nominate an emergency proxy, external to vote for them. However the non-arrival of a postal vote does not qualify.
Scottish Labour leader Anas Sarwar has cast his vote this morning. He was seen leaving a polling station in Glasgow with his wife Furheen and their son Aliyan.
Ulster Unionist Party leader Doug Beattie has cast his vote in Portadown, Northern Ireland.
Labour leader Sir Keir Starmer has arrived at a hall in north London to cast his vote with his wife Victoria.
Democratic Unionist Party (DUP) leader Gavin Robinson has voted in Belfast, alongside his wife.
Our furry friends are now appearing at polling stations across the UK, and we've just received this photo of three of them - Finn, Berry and Pan.
The trio, who waited outside while votes were cast, were all well behaved - until one of them spotted a squirrel.

The BBC, like other broadcasters, isn't allowed to report details of campaigning or election issues while polls are open on the day of the general election.
Today, we won't report on any of the election campaigns from 06:00 BST until polls close at 22:00 BST on TV, radio or bbc.co.uk, or on social media and other channels.
However, online sites don't have to remove archived reports, including, for instance, programmes on iPlayer.
The lists of candidates, as well as the manifesto guides, remain available online during polling day.
Coverage of what's happening on the day will usually be restricted to uncontroversial factual accounts, such as the appearance of politicians at polling stations or the weather.
It'll tend to focus on giving information that will help voters with the process of going to polling stations.

Most of us are likely to be casting our votes today in community centres, church halls and schools - but what about a house?
For more than 50 years, June Thomas's home in Winwick, Northamptonshire, has been one of the UK's quirkiest polling stations.
Voters cast their ballots in a hallway, under a floating staircase.
But Thomas, 80, who has lived at the the Old School House in Church Road for 54 years has to travel a little further to cast her own vote.
She walks 300 yards to the village post box and mails her vote - and she's already done so this election.
You can read her story here.
Scottish First Minister and SNP leader John Swinney has just cast his vote at Blairgowrie in central Scotland.
If you are registered to vote, you will be sent a polling card with your polling number and polling station details.
You do not need to take the polling card with you but it might speed up the process.
You do have to take valid photo ID.
You can only vote at your local polling station, which might not be the same as in previous elections.
You can also find your local polling station online, external.
As we mentioned earlier, polling stations are open until 22:00 BST - and you can vote as long as you are in the queue before 22:00.
In the first of many dogs at polling station pictures coming your way today, we've just got hold of our first one. The honour goes to an eight-month-old cocker spaniel named Maple.
This pup was at a Newbury polling station just after it opened at 07:00.
As we've already explained, we're limited in what we can report between now and 22:00, when polls close, so expect to see plenty of pictures of dogs at polling stations in the meantime.
But it's not just dogs we're interested in.

Prime Minister Rishi Sunak has now voted in North Yorkshire. He and his wife Akshata Murty popped over to their polling station in a village hall, about half an hour after the polls opened.
All across the UK, polling stations have swung open their doors as voting begins. Here are some images of polling officials putting on the final touches.
