Harry also received Scottish and Northern Irish titles, becoming the Earl of of Dumbarton and Baron Kilkeel, which means Meghan will become the Countess of Dumbarton and Baroness Kilkeel.

Tens of thousands of royal fans have begun to descend on the Berkshire town to catch a glimpse of the bride and groom, as police have effectively created a ring of steel around the castle in a massive security operation.

Weather forecasters are expecting wall-to-wall sunshine, meaning the newlywed couple will be able to ride through Windsor town centre in the open top Ascot landau for their carriage procession.

Some 250 members of the armed forces will take part in the pomp and ceremony of the celebrations, with regiments closely connected to former soldier Harry lining the streets.

Meghan will emerge from the hour-long televised ceremony, which begins at noon, as an HRH and a member of the British royal family after saying her vows.

Harry spent his last night as a single man at the exclusive Coworth Park country house hotel in Ascot.

Meanwhile 15 miles away, Meghan stayed with her mother Doria Ragland at the luxury Cliveden House Hotel in Taplow, Berkshire.

Around 30 members of the royal family including the Queen and the 96-year-old Duke of Edinburgh, who is well enough to attend after undergoing a recent hip operation, will gather in the 600-strong congregation.

The Archbishop of Canterbury, who will marry Harry and Meghan, has spoken of the strong bond the couple share.

“There’s profound affection between them which is wonderful and a deep understanding and mutual support,” he said.

“You see in the way they respond to each other, caring for each other, which is something you see in many couples but not always.”

As the Order of Service was published on the morning of the wedding, it revealed Harry will wear a ring – not a given for royal men – and Meghan will not promise to obey her husband in the vows.

The moving, soul classic Stand By Me by Ben E King will be performed by Karen Gibson and The Kingdom Choir, with the gospel singers also delivering Etta James’ uplifting version of Amen/This Little Light of Mine – a favourite in African-American churches.

The presiding bishop of the American Episcopal Church Bishop, Michael Curry will give the address.

The Prince of Wales will take on the role of the absent father of the bride Thomas Markle, and walk his future daughter-in-law through the Quire up the altar to meet her groom.

There will be sadness amid the joy for Meghan with her father missing her big day.

The reclusive former TV lighting director will be thousands of miles away in Mexico after pulling out of attending on medical advice with just two days to go after undergoing heart surgery.

Harry too will be thinking of his late mother Diana, Princess of Wales, who died in car crash when he was 12.
