Donald Trump has appointed his son-in-law, Jared Kushner, as a senior White House adviser.

The appointment which was announced last light will see Kushner, who is married to Trump's daughter Ivanka , work on trade deals and the Middle East.

The 35-year-old's position does not require US Senate confirmation.

Ivanka Trump, who like her husband has been a trusted adviser to the president-elect, will not take on a role in her father's White House but will focus instead on settling her family in Washington.
