no ones yet fully answered the question , some say if your born here your a Scot, Not true, your not even Legally British, for example children of failed asylum seekers, or foriegn nationals without leave to stay or expired visas who have children here get a Scottish Birth certificate simply for stastical purposes, but are not Legally British Citizens, and are certainly not Scots, if you ask the guy down the road in the chip shop if hes a Scot he'll tell you "no I was Born in Scotland but Im Chinese."

Tony Blair, for excample was born in Edinburgh but insists he is English, Sandy Lyle and Bruce Rioch were born in England but are Scots.

is it the Accent? Gordon Ramsay is a Scot born in Scotland to Scots patents but has a southern English accent Id love to hear what he would say if someone claimed he wasnae a Scot.
Many people in the North of Scotland and the islands as well as many Scots aristos have non stereotypical Scots accents that sound English to casual listners,

is it your parents?? if so then what criteria are we using to say that they were Scots.

is it becasue you live here, Alex Salmond says everyone living here is a Scot or a "new" Scot. Ive many English and Irish friends that would be scandalised to be branded as Scots just becasue they live here ,as well as the guy in the chippy.

Is it elligibility to play for the national team, you can play for Scotland if one of your Grandparents was born here
