The ship, which had around 500 men and women on board, was the first to bring workers from the Caribbean who had answered Britain's call to help fill post-war labour shortages.

The King was among those taking part in dozens of events on Thursday when he attended a service in Windsor after describing the Windrush generation's legacy as "profound and permanent".

Events were also held at London's Southwark Cathedral and the Port of Tilbury, Essex, where the ship docked on 22 June 1948.

Other events include exhibitions at museums across the UK and a carnival parade through the streets of Brixton in south London, while the Windrush flag was being flown at major landmarks such as the Houses of Parliament.

Patrick Vernon, convenor of the Windrush 75 network, which is organising many of the events, said it was a chance to "celebrate the diversity of modern Britain" and to "acknowledge the legacy of those first Windrush pioneers, the challenges they overcame and the contribution they made to Britain".

But he added it was a "bittersweet moment, tainted by the injustice of the Windrush scandal".

In 2018, it emerged that many who made legitimate journeys to Britain had been wrongly detained and deported, despite having the right to live in the UK.

Many lost homes and jobs and were denied access to healthcare and benefits. Some of those deported later died before they were able to return to Britain.

The then prime minister Theresa May later apologised and an inquiry led to the establishment of a compensation scheme for victims.

However, the government has been criticised for being slow to pay out, amid claims the process places an unfair burden of proof on claimants.

Earlier this year, Human Rights Watch called for the Home Office to hand over control of the "hostile" scheme to an independent body instead.

Labour MP Dawn Butler said on Thursday that many were still "in limbo" and accused ministers of not caring about the fate of victims.

She told Sky News: "I think the government strategy is to wait for people to die. I think they want people to die.

"We're talking about pensioners, in their 70s and 80s, waiting to be compensated for the life that was taken away from them - and this government is dragging their feet."

Home Secretary Suella Braverman has also been criticised for dropping three of 30 recommendations from the inquiry's report.

But the Home Office has rejected the criticism and insists it is "absolutely committed to righting the wrongs of the Windrush scandal".

So far £75m compensation has been offered to victims, with £62.7m paid out, according to latest official figures for May.

Ministers say there is no time limit or cap for the scheme.

The government said Thursday's procession in Brixton was one of 45 community projects, including a series of commemorative cricket matches in Sheffield, funded by its £750,000 Windrush Day Grant Scheme.

Lee Rowley, communities minister at the Department for Levelling Up, Housing and Communities, said: "The events taking place today and all this week are a chance to reflect upon and recognise those who have done so much to strengthen the life of our nation."

Last week, the King and Queen met 10 Windrush pioneers at Buckingham Palace to celebrate a series of portraits marking the 75th anniversary.

A new commemorative 50p Windrush coin was also unveiled by the Royal Mint earlier this week.
