Secret Service in golf buggies, soldiers scouring the sand dunes, and police boats bobbing offshore - welcome to Operation Birdie...

A huge security operation was underway at Trump Turnberry today as the US President begins the first full day of his visit to Scotland.

Donald Trump touched down at Prestwick Airport on Friday night, and is now staying at his famous golf resort - where he is expected to hit the fairways later today.

The trip has now commandeered almost a third of Police Scotland's manpower and this morning officers in high viz vests were seen swarming over greens, tees and fairways, while snipers overlooked it from watchtowers.

Police also have road closures in place, with limited access for locals and members of the media. Amid the search, a few golfers were also spotted at the course, enjoying an early-morning game.
