The strict religious laws (and police) within Saudi Arabia goes back centuries, and anyone who chooses to live there, or even just visit, are very aware of them.
I don't know about now, but it used to be a bit of a game trying to smuggle bottles of spirit/beer kits into some Muslim states e.g. Kuwait, and if you were caught by customs and saying that it was for personal 'medicinal reasons' didn't work, they would just lift it.
Sometimes it was better to take brand lesser quality bottles as gifts to expats there, to increase the success ratio, as you never knew who would end up using it e.g. choosy customs officers.
But NO ONE ever tried that going into Saudi Arabia, where luggage was searched and even if a book cover somehow offended, meant it was confiscated.
Jeddah being on the Red Sea and full of palm trees to many even feels like a holiday location, but you just have to get used to 'cocktails' etc have no booze within.
I feel very sad for this gentleman for several reasons, the lashes being the most obvious, but anyone needing to remain in the tax free (still?) Saudi Arabia into their mid 70's totally missing a tipple they could have at any time here during retirement - has to be for financial reasons, and there are clues that is so.
Islam in Saudi Arabia
en.wikipedia.org/wiki/Islam_in_Saudi_Arabia
In the 18th century, a pact between Islamic preacher Muhammad ibn Abd al-Wahhab and a regional emir, Muhammad bin Saud, brought a fiercely puritanical strain of Sunni Islam first to theNajd region and then to the Arabian Peninsula. Referred to by supporters as "Salafism" and by others as "Wahhabism", this interpretation of Islam became the state religion and interpretation of Islam espoused by Muhammad bin Saud and his successors (the Al Saud family), who eventually created the modern kingdom of Saudi Arabia in 1932.

I would suspect that having found stuff in his car, after the 1-year jail term he has already served, the mention of lashes now is to GET the UK authorities to intervene - and the deal they want to strike is to DEPORT him, WITHOUT corporal punishment.
God willing.
