Tarek Naggar is said to be critically injured and in intensive care after he was attacked on the island of Cebu.
The 44-year-old, from Milngavie in East Dunbartonshire, was confronted by three men on a scooter as he sat outside a bar in Cebu City early on Thursday morning with his fiancee Angie and his best man Chris McLaughlin.
According to the Sunday Herald, the men had demanded he hand over his wallet – and when he refused, one of them pulled out a pistol and shot him in the chest.
They then made off with his wallet, which contained credit cards and local currency worth less than £10.
Mr McLaughlin told the newspaper that Mr Naggar has undergone surgery and has been put on a life-support machine after the bullet lodged in his lung.
A spokeswoman from the Foreign and Commonwealth Office said: “We are assisting a British national who was shot during a robbery in Cebu, Philippines, and are in touch with local authorities.” (SKYNEWS)
