Donald Trump begins his official work day as late as 11am and is known to clock off at 6pm, leaked copies of his private schedule reportedly reveal.

The US president often has ill-defined “executive time” scheduled in the early morning and at other points in the day, according to the political website Axios.

The periods are used for Mr Trump to make phone calls, watch television and send tweets, it was claimed – often from his private residence in the White House.

The late official start contrasts with Mr Trump’s early months in the White House and with previous presidents.

George W Bush typically arrived in the Oval Office by 6.45am while Barack Obama would work out before holding meetings from 9am or 10am.

A White House spokesman defended Mr Trump as “one of the hardest workers I have ever seen” and said he works when in the residence.
