The long-awaited first kiss of the newly married couple drew cheers and applause from those gathered in the baking heat outside the West Door.
There were shouts of “Congratulations”, followed by a cheeky “Don’t be shy” from a former soldier, as he hinted for a second kiss.
Paul Vice, an ex-marine said Harry, who he has met a number of times, smirked back at him and would have been well aware of the squaddie humour with which the shout was intended.
Mr Vice joked: “As soldiers we’ll always give him a little bit of flack, especially now he’s under the ball and chain.”
The 34-year-old from Exeter, who is a past participant in the Invictus Games, said he believed even if Harry felt nervous as he arrived he would not have shown it.
“He’s a good lad, he looks very happy,” he said.
Harry and Meghan were met with a wall of cheering and flag waving as the procession made its way through the streets of Windsor.
The pair smiled and waved to well-wishers during the journey in the lunchtime sunshine.
They are heading to St George’s Hall for a lunchtime reception hosted by the Queen.
