Donald Trump has declared Alex Salmond “an embarrassment to Scotland” after remarks by the MP on his radio show continued a public spat between the pair.
Mr Salmond suggested the US billionaire had overstated his investment in Aberdeenshire and his ownership of the prestigious Turnberry golf resort could actually lose the country money.
The former SNP leader and first minister was responding to a question during the first broadcast of his new phone-in radio show on the LBC network.
Republican presidential candidate Mr Trump responded by saying Turnberry had suffered from under-investment until he took the reins and accused Mr Salmond of destroying sections of Scotland’s landscape with wind turbines.
He also recalled the Scottish Government’s “disgraceful” decision to release Lockerbie bomber Abdelbaset Al-Megrahi on humane grounds in 2009.
Mr Trump said in a statement: “Megrahi and others were laughing out loud at what a stupid man Alex Salmond is.
“Why would a terrorist that blew up an airliner with so many lives lost be released under any circumstances? Alex Salmond is an embarrassment to Scotland.”
On his business interests, Mr Trump said: “For a long period of time Turnberry, while always successful, was not properly reinvigorated with the massive amounts of capital necessary.
“I am investing a minimum of £200 million initially including rebuilding and renovating the great Ailsa course, a new second course and the total renovation of the magnificent Turnberry hotel which is already under construction.”
The property developer established the Trump International Golf Links at the Menie Estate in Aberdeenshire and had the support of Scottish ministers before a fall-out over a proposed offshore wind farm project which he claims will spoil the view from the resort.
He said future investment at Menie and Turnberry are at risk if he is banned from the UK following controversial comments about Muslims he made on the campaign circuit.
Mr Salmond told an LBC caller he had changed his mind about Mr Trump for two reasons.
He said: “Having secured his development, which was controversial, he then objects to other developments, like the offshore wind demonstrator – which would be generating some badly-needed jobs in the north-east of Scotland.
“Secondly, his comments about banning all Muslims from America. If anybody else was saying that sort of thing, if it was a preacher or something, he’d be banned from the UK for that sort of racist stuff.”
On Turnberry, the MP said: “As long as Donald Trump owns Turnberry I think it’s impossible, actually, for the Royal and Ancient to take the Open there.”
Mr Salmond, the SNP’s spokesman on international affairs, subsequently hit back following Mr Trump’s latest remarks.
He said: “His claims of the level of future investment in Scotland bear no resemblance to the reality of the last eight years.
“His ownership of Turnberry places it effectively out of The Open Championship circuit at a cost of £100 million to the Scottish economy.
“His legal objections to wind demonstrators in Aberdeen have thus far deprived the north-east of Scotland of a vital £200 million diversification into offshore wind technology at a time of great difficulty in oil and gas.”
