President Donald Trump's planned state visit to the U.K. has been delayed until next year, Reuters reported. British Prime Minister Theresa May invited Trump to London during her January White House visit but, according to a senior U.S. administration official, the two leaders were unable to schedule a date that works for both sides. “It's just a scheduling issue,” the official told Reuters. “Finding a date that works for everyone turned out to be difficult. We're looking at next year.” Trump has been to Europe twice since taking office and will be in Paris later this week. The British Parliament earlier this year debated whether to rescind the invitation.
