The Duke and Duchess of Cambridge have celebrated St Patrick's Day with a parade by soldiers from the Irish Guards.
Kate and Prince William, who is Colonel of the Irish Guards, were visiting personnel from 1st Battalion at their base in Hounslow, west London.
The parade began with the Last Post, before a minute of silence was observed in memory of the 50 victims killed in the attacks on two mosques in New Zealand.
The Duchess presented the shamrock to Officers and Warrant Officers and three cheers were raised to the couple before a march past where Prince William took the salute.
350 soldiers marched on the Parade Square at Cavalry Barracks.
Leading the procession was Irish wolfhound and regimental mascot Domnhall, whom the Duchess stroked while presenting him with a shamrock.
Drummer David Murray, his regimental handler, said the St Patrick's Day parade was "number one" in his calendar and like a "second birthday".
The mascot was presented with his first shamrock in 2013 and led the regimental band and parade.
Drummer Murray said: "We've had a week-long preparation as a battalion, we've had a couple of rehearsals, couple of little bits that we've had to obviously fine tune.
"Domhnall - he's been in the battalion since 2012, he's pretty good at his job... doesn't really need to fine tune much so in regards to me and him it's been quite a smooth week.
"He helps me through the parade to be honest, he knows what he's doing."
Warrant Officer Class 2 Ryan Orr told Forces News: "Today [St Patrick's Day] is very important to the Battalion.
"We're a family regiment so it's good to have us all together to celebrate together as a family, like we always do.
"With the Battalion due to deploy to South Sudan and Iraq, it's massive because this year is going to be a big year for the Battalion."
Last October, Prince William visited the Irish Guards at the British Army Training Unit Kenya, while on a tour of Africa where he was promoting his conservation project.
The couple also visited personnel based at RAF Akrotiri in December to thank them for their dedication over the Christmas period.
