He said: “I actually think the reverse. No-one really knows what it’s going to mean from a commercial point of view. There are going to be so many things to be worked out that to add Scottish independence on top would be foolhardy.”Sir Tom, who made £290 million from the sale of the Sports Division business to JJB Sports in 1998, told The Herald that Brexit had not made him less likely to invest in the UK, but he expressed concern about the lack of information on what Brexit would mean in practice.He did not publicly back Yes or No in 2014 but has called since for Scotland to “move on” from the vote and for the parliament to use its new powers.In September last year he urged party rivals to unite and “focus upon building a more prosperous, productive and fairer Scotland where opportunity prevails for all”. He added: “The population decided, politicians are democratically elected and should and must respect the decision of the voters.” Nicola Sturgeon launching her Brexit proposals One of Scotland’s leading entrepreneurs has said he cannot understand why Nicola Sturgeon wants to keep Scotland in the EU while taking it out of its “biggest trading union” with the rest of the UK.The First Minister has warned a second independence referendum remains “highly likely” if Scotland is not able to remain in the single market.But Sir Tom Hunter, the sports and property tycoon, said a new vote would be “foolhardy” because of the uncertainty surrounding the Brexit process.He added: “There’s enough uncertainty for us all to deal with. I can’t quite understand why the government wants to take us out of one union which is our biggest trading union but keep us in another one.“I really do think it would be the wrong thing to bring up another independence referendum at this point. I’m not saying never, just not now.”The millionaire businessman also rejected suggestions that Scotland’s vote to remain in the EU had boosted the case for breaking up the UK.

Ms Sturgeon unveiled her plan to keep Scotland in Europe on Tuesday, when she presented three options for remaining in the single market and was accused of trying to exploit Brexit to achieve independence by the back door after demanding a swathe of new powers.Her blueprint involved Holyrood getting some control over issues ranging from immigration to business regulation and international trade negotiations.She also rejected warnings from a series of academics that Scotland and England having different business and immigration regimes would lead to a hard border between the two.Theresa May later poured cold water on the proposals, telling MPs not to assume that Scotland would get a “differential” deal. Meanwhile, the SNP accused the UK Government on Friday of recklessly causing “six months of damaging uncertainty” to the economy and society.Stephen Gethins, the party’s Europe spokesman, said ministers had continued the “gross irresponsibility and negligence” of the Leave campaign by refusing to give any details about what leaving the EU will mean beyond “meaningless slogans”.
