The roar from two F35 Lightening fighter jets, escorting the King and Queen as they landed safely in Rome, ensured the State Visit began in style.
As we arrived on the tarmac ahead of Their Majesties' arrival, we observed the guard of honour (made up of the Italian Navy, Italian Army and Italian Air Force personnel) rehearse an official welcome - a NATO ally on the world stage.
The greeting of dignitaries on the red carpet, including the UK Ambassador to Italy, Lord Llewellyn, and Foreign Secretary, David Lammy MP, was relatively short-lived.
Described as an "administrative arrival," we are not expecting full pomp and pageantry until the State Welcome on Tuesday morning. This is when we expect the British National Anthem to be played, and a joint flypast between the RAF Red Arrows and Italy's Frecce Tricolori. Before the King and Queen landed, I walked around Rome's ancient Colosseum.

Weaving in and out of crowds of tourists from around the world, there was little indication a State Visit from King Charles and Queen Camilla was imminent.
However, gossip amongst locals is ramping up - both in Rome and Ravenna.
"Royal Fever Rising" was the headline in one local newspaper in Ravenna recently, perhaps indicating the Italian people are growing increasingly excited about the visit.
The UK Ambassador to Italy, Lord Llewelyn, even claims the owner of his local pizzeria has asked about the King's visit every time he eats there.
It appears the Italian buzz for King Charles started way before this State Visit was planned, even if one doesn't count his seventeen previous visits as the former Prince of Wales.

While embarking on the surprise walkabout, he told an Italian television news crew: "I love Italy."
Lord Llewelyn believes the "feeling is mutual", indicating the UK Government is well advised to send King Charles to strengthen bilateral relations between the UK and Italy.
The UK Ambassador told us: "This visit will deliver a meaningful and broad legacy. Above all, Their Majesties will do something intangible but priceless.
