WASHINGTON: Following his proposal to temporarily bar Muslims from entering the country, Donald Trump has increased his lead in the Republican primary to its largest margin yet, according to a new Washington Post-ABC News poll.

The results are the latest sign that Trump’s outspoken comments on immigration and terrorism continue to find an audience among rank-and-file Republicans in spite of sharp condemnation from Democrats, GOP leaders, some of Trump’s rivals and a chorus of world leaders.

Separately, sources said Britain’s top court will decide on Wednesday whether to back Trump’s bid to stop wind farms being built near his luxury Scottish golf resort amid a growing spat with politicians in his mother’s homeland.

Former Scottish nationalist leader Alex Salmond even described the property tycoon, who is leading the polls to be the Republican candidate in 2016, as “crazy.”

Trump said: “I have done so much for Scotland, including building Trump International Golf Links, Scotland, which has received the highest accolades, and is what many believe to be one of the greatest golf courses anywhere in the world.”

“The UK politicians should be thanking me instead of pandering to political correctness,” he added in an article for Scotland’s Press and Journal newspaper.

Trump wants to sink a plan by Scotland’s government, run by the Scottish National Party, to erect 11 offshore turbines off Blackdog in Aberdeenshire on the northeastern coast of Scotland because he believes they will spoil the view from the nearby greens of his golf complex.

The government argues the $350 million European Offshore Wind Deployment Center would boost the local economy and power 49,000 homes.

Trump has already lost a series of battles in Britain’s lower courts and his last chance to block the plans rests with the Supreme Court, the country’s highest judicial body.

“Mr Trump does not want a wind farm 1 km (half a mile) away from his golf course,” his lawyer John Campbell said when the matter went before the court in October.

The case hinges on prosaic rather than aesthetic, environmental or political issues: Trump’s team are disputing the validity of the Scottish government’s approval of the wind farm and its interpretation of the 1989 Electricity Act.

Trump’s representatives in Britain said they would not comment until after the judgment.
