Donald Trump responded defiantly last night to the news that the petition will be debated by MPs.
George Sorial, executive vice-president of the Trump Organisation, warned any action to restrict his travel would force the company to “immediately end” all current and future investment in the country.
He told the Press and Journal it would send a “terrible message to the world that the UK opposes free speech” and has no interest in attracting inward investment.
He added: “This would also alienate the many millions of US citizens who wholeheartedly support Mr Trump and have made him the forerunner by far in the 2016 presidential election.”
Pointing to the US presidential hopeful’s success in the polls, Mr Sorial continued: “Many people now agree with Mr Trump that there is a serious problem that must be resolved.
“This can only be achieved if we are willing discuss these tough issues openly and honestly.”
Mr Sorial said the Trump Organisation had plans to invest more than £200million developing the Trump Turnberry resort in South Ayrshire.
He also highlighted plans to invest £500million in Trump International Golf Links at Menie in Aberdeenshire.
“It has been consistently rated the best modern golf course in Great Britain and Ireland by the prestigious Golfweek magazine and many others in the global golf community,” he added.
The fact the petitions committee has granted a debate does not mean the UK Government will be forced to act.
The motion debated will simply be that the House has considered both the petition calling for Mr Trump to be blocked from UK entry and its counter.
Home Secretary Theresa May has the power to exclude an individual if she considers that his or her presence is “not conducive to the public good or if their exclusion is justified on public policy grounds”.
But the government has repeatedly rejected calls from SNP MPs and others.
