In case Donald Trump wins the presidency of the United States in November 2016, he could face a world where many leaders, including U.S. allies, might not be too eager to congratulate him warmly based on the recent statements they made on him.

These leaders have spoken out against Trump after he called for a ban on Muslims entering the United States.

CNN has compiled a partial list of these leaders and what they said about the Republican presidential front-runner.

● British Prime Minister David Cameron, in an unusual statement, called Trump's remarks "divisive, unhelpful and quite simply wrong."

● London Mayor Boris Johnson rejected Trump's comments that parts of London are strongholds of radical Islam off-limits even to the police, calling such remarks as "complete and utter nonsense." Britons were apparently so incensed of Trump that a petition to ban him from traveling to the U.K. had nearly 600,000 signatures as of Friday afternoon.

● Israeli Prime Minister Benjamin Netanyahu, in an official statement, repudiated Trump's proposal on a Muslim travel ban, prompting the GOP presidential candidate to cancel a planned December trip to Israel to meet with Netanyahu.

● Canadian Foreign Minister Stephane Dion also rejected Trump's comment, saying, "It's something that we cannot accept in Canada."

● French Prime Minister Manuel Valls said Trump "feeds the hatred and the confusion." He also compared Trump to the country's far-right nationalist party, Marine Le Pen, who promptly rejected the comparison. Interviewed by The New York Times, Le Pen said, "I defend all the French people in France, regardless of their origin, regardless of their religion."

● Dutch Foreign Minister Bert Koenders called the billionaire's remarks "very unhelpful and very discriminatory."

● Alwaleed Bin Talal, a member of the Saudi royal family and business magnate, tweeted that Trump was a "disgrace not only to the GOP but to all America. Withdraw from the U.S presidential race as you will never win."

● Qatar Airways CEO Akbar Al Baker said "coming out from a friend of mine, I didn't expect him [Trump] to be so naïve to make such statements," adding that he would "not be welcome" in Muslim countries.

Aside from these statements, some companies have taken action against Trump. The Dubai-based home decor chain Lifestyle, for instance, is removing all Trump-branded products from its 195 stores across the Middle East, North Africa, Pakistan and Tanzania. Trump's name and image have also been stripped from his golf project in Dubai.
