Alistair and Rowan - Separated at birth

I opened the dusty file and checked the documents, there was no doubt that these two were brothers. The paperwork was almost irrelevant, it was as clear as the ridiculous grin on both of their faces.
Even though they had never met there were remarkable similarities in their colourful past that hinted at a genetic link and a predetermined behavioural pattern.
Both had been brought up in very privileged circumstances, educated at various private schools leading unswervingly to a top university education. Both of them had rebelled against the direction taken by their fathers, and both had strong family links to the world of politics.

There was a note pencilled at the bottom of the page, an explanation of the premature loss of cranial pigmentation to one of the brothers - the details were unclear but the words "traumatic experience," "flock of sheep" and "rarified highland air" were still easily discernable.
One of the brothers had risen to the top of his chosen profession and become a well-known household name, putting his signature to many important scripts and televised events - the other had also often been seen on prime-time television, but had assumed the role of a bumbling idiot.
At that moment there was a knock on the door - I quickly replaced the file into the cabinet and quietly closed the drawer. An East Lothian accent asked, "Would ya like a wee dram afore ye go?" I declined and left hurriedly.
