Sir Keir Starmer has pledged "national renewal" as the government outlined its plans during the King's Speech
They include nationalising railway operators and speeding up the delivery of "high-quality infrastructure and housing" - but there's no specific mention of votes for 16-year-olds
Also in the speech was charging VAT on private school fees, and using "counter-terror style" tactics to stop cross-Channel people smuggling
The government announces a new child poverty taskforce, but Starmer faces some pressure on not scrapping the two-child benefit cap
Rishi Sunak says his party will oppose the government where necessary - but not for its own sake
Labour's first King's Speech: What happened in 60 seconds
As the King makes his way to Parliament, the crown is already there.
The Imperial State Crown - along with the Cap of Maintenance and the Sword of State - arrived at the House of Lords a few moments ago. Here's a closer look...

Image source, PA MediaThe King and Queen are going to get a comfortable ride clip-clopping up from Buckingham Palace, travelling in the Diamond Jubilee State Coach.
It looks glittering and ancient, but in fact has only been in use since 2014 and has air-conditioning, hydraulic suspension and electric windows.
There is history literally built into this modern carriage, though, with the design including bits of wood from HMS Victory, the Mary Rose and Westminster Abbey. Appropriately for this event, it also includes material from No 10 Downing Street.
In another tradition - or oddity depending on your view - symbols such as the crown, sword of state and the cap of maintenance travel in a separate carriage, which has already happened
When they all get to Westminster, King Charles will wear the Imperial State Crown.
And they’re off.
Escorted by the Household Cavalry, the King and Queen have just set off from Buckingham Palace to begin the carriage procession to Westminster.
The short journey down Mall, along Whitehall and finally to Parliament, will end when the horse-drawn coach reaches the Sovereign’s Entrance.

Image source, Getty ImagesWe have just seen the Imperial State Crown - considered one of the most valuable pieces in the Crown Jewels - leave in a carriage from Buckingham Palace ahead of the King.
The crown, which gets its own private escort, weighs 2.3 lbs (1.06kg)and has nearly 3,000 stones - including 2,868 diamonds, 273 pearls, 17 sapphires, 11 emeralds, and five rubies.
Ten members of pressure group Youth Demand have been arrested in Westminster, the Metropolitan Police says.
All were arrested on suspicion of conspiracy to cause public nuisance after the protest group stated it planned to disrupt the State Opening of Parliament.
It's Keir Starmer's first State Opening of Parliament since becoming prime minister - and here he is leaving Downing Street a short time ago to make the short journey to Westminster.

We're expecting housing and planning to be big parts of today's King's Speech - with the aim of bringing the cost of home ownership and renting down.
New figures from the Office for National Statistics (ONS) show average house prices in the UK increased by 2.2% to £285,000 in the 12 months to May 2024.
Average UK private rents increased at a faster rate - by 8.6% in the 12 months to June 2024.
Both those figures are above the inflation rate we brought you earlier, which was was unchanged in June at 2%.

As we reported on Monday, the King’s Speech will include measures to create a standalone offence of spiking.
It’s something Labour promised in its manifesto.
Although spiking (via drinks or another method) can be prosecuted under current laws, ministers believe a specific law will help police crackdown on spiking.
I’d also expect to see Martyn’s Law return. It’s named after Manchester Bombing victim Martyn Hett and will see venues required to have stronger protections to prevent terror attacks.
You might remember Martyn’s mother criticising Rishi Sunak for calling the election before the legislation was passed in the last Parliament.

We earlier reported Labour's Pat McFadden discussing what will be in the King's Speech.
But something that won't be included is scrapping the two-child benefit cap.
Speaking to the BBC's Good Morning Scotland, McFadden reiterated that Labour won’t scrap the cap.
Pressed on whether the policy was harmful to children living in poverty, he eventually responded "whether it causes harm will be open to debate".
That comment has been seized on by the SNP. Their Westminster leader Stephen Flynn labelled the comments "extraordinary".
This could prove an uncomfortable issue for Scottish Labour.
Their leader, Anas Sarwar, opposes the cap – and it’s been an awkward topic for him and Sir Keir Starmer to navigate in their relationship.
Now we've done the explosives and hostages, let's get back to policy.
In the King's Speech, the government is expected to set out how it plans to tackle migrants crossing the Channel in small boats.
The Labour manifesto committed to a new Border Security Command , externalwith counter-terror powers, which it says will be "a major step change in UK enforcement efforts to tackle organised immigration crime".
But Peter Walsh, senior researcher at the Migration Observatory, tells BBC Radio 5 Live it is hard to see how Labour's plans will be different to what is already in place.
Walsh adds that while the counter-terror powers would be an addition, details are currently lacking - and such powers would likely need cooperation from France.
"At the moment it’s really unclear whether that [the proposed border security agency] will be the game-changer that Labour hopes," he says.

Another bit of tradition comes soon when an MP is taken "hostage" - to be held at Buckingham Palace while King Charles III is in Parliament.
The idea is to ensure the King's safe return - and it dates back to the English Civil War when Charles I had a contentious relationship with Parliament, and was eventually beheaded.
The hostage is the person who's the Vice Chamberlain of His Majesty's Household, external - an MP who is also officially a member of the Royal Household, and a junior government whip.
This year's hostage is Samantha Dixon, the Labour MP for Chester North and Neston.

Although the King's Speech doesn't begin until 11:30 BST, the State Opening of Parliament officially begins in 15 minutes' time.
This is when the King's bodyguards - known as the Yeomen of the Guard - carry out a ceremonial search, external of the underground cellars of the Palace of Westminster.
What are they looking for? Explosives, of course.
It's a nod to the Gunpowder Plot of 1605 when a group of English Catholics tried, and failed, to blow up the Protestant King James I and Parliament.
Our colleagues on Radio 4's Today programme have just spoken to the Lib Dems' Munira Wilson.
Asked if the party would support the government's planning reforms - which are expected to allow some parts of the green belt to be redesignated as "grey belt" - she says: "Liberal Democrats have said we shouldn't be building on our green belt", adding: "We think you need to start with brownfield sites."
Asked if they would support expected government plans to prevent local people objecting to "critical national infrastructure" (such as wind or solar farms), she says people should be offered something in return.
"The way to incentivise local communities to buy into these schemes is to say, well actually, if we're going to have a solar farm...you will benefit from this by getting reduced prices on the energy that you're generating locally," she says.

Queen Camilla - who will accompany the King for the state opening - is celebrating her 77th birthday today.
Any birthday dancing, though, might be curtailed after she sprained her ankle on a visit this week to the Channel Islands.
She was born on 17 July 1947 in King’s College Hospital in Denmark Hill, south London.
The same obstetrician also went on to deliver the then Prince Charles - born the following year in Buckingham Palace.
Here's a bit more from Labour's Pat McFadden, who has just been speaking to our colleagues on Radio 4's Today about what "getting Britain building again" will mean.
He's asked about those who want to see new houses built and cleaner power - but don't want a new estate or electricity pylons in their back yard.
McFadden tells the Today programme the government will look to build on brownfield sites first - old industrial or inner-city sites that have been cleared.
But he acknowledges there will always be "controversial" planning applications. "In the end the country has to make a decision," McFadden says.
"Once this goes through, if we are a country where it is more realisable for young people to own their own home, or rent one at a decent price, we will get the growth the country needs and overall the country will benefit."

Image source, ReutersOne of the bits of law that didn’t make it through the last Parliament was a bill to introduce an independent football regulator.
Both Labour and the Conservatives committed during the election to bringing one in - and it’s sounding very likely that the bill will reappear in today’s King’s Speech.
It will include a strengthened fit and proper owners test - that’s the process to decide who is and isn’t allowed to own a football club.
Labour’s test has three elements:
But the Premier League wants to continue carrying out its own test too.
So if they say a prospective owner is fit and proper - and the new regulator says they’re not - whose decision is the one that matters?

It is worth saying that government plans and government achievements are not the same thing.
Ideas for new laws can get bogged down, side-tracked, amended, and a government can run out of time or enthusiasm to pursue them.
And stuff happens, stuff always happens, that seizes the agenda, the attention, the in-tray of ministers.
But remember this is a government with a mountainous majority.
Rebellions and noises off would have to be mighty loud to cause Sir Keir Starmer real problems and while there is no doubt that in time there will be an awkward squad on his benches, most are likely to be loyal before they (potentially) get grumpy.
For the prime minister today, the aim is to project a sense of energy and urgency, but not surprises.
He will try to convince you he is turning his campaign promises into reality, or at least beginning the process of doing so.
And he wants to give off the impression the party has been working hard in opposition to be ready for government - that the scale of these ideas make it obvious they have not been cobbled together in the last fortnight.
Labour want to make the most of any honeymoon period, which they know will probably be short-lived. They successfully harnessed that most powerful of words - "change" - in the election campaign.
Now comes the next difficult bit: actually trying to deliver it.
