Getting rid of the "imperialist baggage" of the UK state through Scottish independence will present new cultural and political opportunities, according to author Irvine Welsh.
In an article published online, in which he describes his early life visiting relatives in London, Welsh argues that political separation could promote cultural unity.
He suggests that expressions of Britishness - as displayed during last summer's Olympics - will continue, also proposing that the British team could remain after independence.
On wider political issues, he considers that the peace process in Northern Ireland could be encouraged if the Irish Republic feels more like part of a "shared geographical" entity with Britain.
"This state has stopped England from pursuing its main mission, namely to build a inclusive, post-imperial, multi-racial society, by forcing it to engage with the totally irrelevant (from an English perspective) distractions of Scotland, Wales and Northern Ireland," he wrote on the Bella Caledonia website.
"From the viewpoint of the Scots, it has foisted 35 years of a destructive neo-liberalism upon us, and prevented us from becoming the European social democracy we are politically inclined to be. Therefore I'm advancing another proposition: political separation could promote the cultural unity that the UK state, in its current form, with its notions of 'assumed Englishness' is constantly undermining."
He refers to last summer's Olympic celebrations, put together by director Danny Boyle, who turned Welsh's book Trainspotting into a hit film.
"Despite the shallow flag-waving social engineers in Government and sections of the media, who tried to turn it into a bread-and- circuses propaganda event, the Olympics were the best expression of inclusive Britishness we've had for decades," he argued.
"Danny Boyle, in a couple of hours, did more to assert democratic socialist values over neo-liberalism than the UK Labour Party has managed to do in almost 40 years. But it was also nostalgic; it mirrored not just what many of us still aspire to, it showed us what we have to accept we've irredeemably lost.
"But I cheered just as ecstatically when Brad Wiggins crossed the line as when Chris Hoy did, and plenty other Scots I know did too. So post UK, why not, for example, just keep the British Olympic team?"
