'Minor electrical issue' on Air Force One delays Trump Davos visit

Key Highlights

• Trump has repeatedly voiced dissatisfaction aircraft.
• Last year, his administration announced it was "looking at alternatives" to Boeing following repeated delays in the delivery of two new aircrafts.
• In May, Washington was criticised for accepting a $400m (£301m) Boeing 747-8 donated by Qatar as an "unconditional" gift, with any necessary retrofitting costs being borne by the US government. The White House has insisted that taking the aircraft is legal and pledged that it will be donated to Trump's presidential library once he leaves office.
• Trump's Davos speech is currently slated for 14:30 (13:30 GMT).
• It's not clear how the delay will impact his schedule, which includes meetings with other foreign leaders and a reception of business leaders. On Tuesday, Trump said he would use the speech to tell European leaders "we have to have" Greenland, as the diplomatic row widens over Trump's threats to acquire it. The president has insisted that the US must acquire Greenland for national security reasons and has not ruled out using military force in doing so. His demands have been rejected by Greenland's leaders, and by Nato member Denmark, of which the island is a semi-autonomous territory.
