Royal Mail has unveiled four new stamps to celebrate King Charles III's Coronation.

The new regal stamp set depicts the King's crowning and the diverse range of causes the monarch has supported over the years. 

Based on newly commissioned wood engravings from artist Andrew Davidson, the four stamps all have their own unique meaning including the Coronation, Diversity and Community, The Commonwealth, and Sustainability and Biodiversity.

This is the third time in history Royal Mail has issued stamps to mark a coronation with the first being for King George VI in 1937 and Queen Elizabeth II in 1953.

The mail service is also applying for a special postmark to be stamped on letters in honour of the royal occasion which will read as: “Coronation of Their Majesties King Charles III and Queen Camilla 6 May 2023”, and run from April 28 until May 10.

Simon Thompson, Royal Mail chief executive, said: “Royal Mail is proud to issue this set of commemorative stamps which celebrate the coronation, and some of the causes which His Majesty has championed throughout his many years of public service.

“This is only the third time we have issued Coronation stamps and I am delighted that they mark the start of a new reign and a new chapter in our history.”

Depicted in regal purple ink, this stamp portrays a Coronation scene that has a backdrop of the front of Westminster Abbey.

Fireworks are going off in the sky above as a gun salute is fired.

Crowds are also seen watching the ceremony and celebrating at a street party.

King Charles's likeness is also featured on the first class stamp where the monarch is seen sitting in the Coronation chair holding the Sceptre with Dove and the Sceptre with Cross.

Figures representing the Jewish, Islamic, Christian, Sikh, Hindu and Buddhist religions hold prominence in Royal Mail's blue 1st class Diversity and Community stamp.

This commemorative stamp has been described as it being representative of all faiths and none by the Royal Mail.

The blue background scene also captures rural and urban Britain and the varied places of worship found around the UK including a church and a mosque.

Royal Mail's red Coronation stamp commemorates the monarch's position as the Head of the Commonwealth. 

The £2.20 stamp imagines a Commonwealth meeting alongside a depiction of the Commonwealth Games and some of the flags from the Commonwealth nations.

It also recognises trade and commerce through industrial scenes whilst also paying tribute to the fallen by including a Commonwealth War Graves cemetery.

The green Sustainability and Diversity stamp

The green stamp is representative of Sustainability and Biodiversity - a cause which is particularly prevalent to the new King since he has spent decades campaigning on environmental and climate change issues.

The regal engraving shows a beekeeper and a hedge layer against a natural backdrop of renewable energy sources like hydroelectric power and solar panels being used as well as sustainable farming methods.
