Reince Priebus, chairman of the Republican National Committee (RNC), will be his chief of staff.

In this role, he will set the tone for the new White House and act as a conduit to Congress and the government.

Stephen Bannon, from the right-wing Breitbart News Network, will serve as Mr Trump's chief strategist.

Mr Bannon stepped aside temporarily as Breitbart's executive chairman to act as Mr Trump's campaign chief.

The Republican candidate defeated Democrat Hillary Clinton in Tuesday's presidential vote, in a result which shocked many, who had expected Mrs Clinton to win following favourable opinion polls.

Mr Trump is due to take over at the White House on 20 January, when Barack Obama steps down after two terms in office.

On Sunday night the president-elect spoke to Chinese President Xi Jinping. The two agreed to meet at "an early date", Chinese state media said.

Representatives for Mr Trump, who has repeatedly accused China of unfair trade practices, said the two leaders established "a clear sense of mutual respect".

Meanwhile in the president-elect's first interview, with US broadcaster CBS, Mr Trump said:

    He would deport or jail up to three million illegal migrants with criminal links
    Future Supreme Court nominees would be "pro-life" and defend the constitutional right to bear arms
    He will not seek to overturn the legalisation of same-sex marriage
    He will forgo the president's $400,000 salary, taking $1 a year instead

"I am thrilled to have my very successful team continue with me in leading our country," Mr Trump said in a statement released by his campaign.

"Steve and Reince are highly qualified leaders who worked well together on our campaign and led us to a historic victory. Now I will have them both with me in the White House as we work to make America great again."

Mr Priebus, 44, acted as a bridge between Mr Trump and the Republican party establishment during the campaign.

He is close to House Speaker Paul Ryan, a fellow Wisconsinite, who could be instrumental in steering the new administration's legislative agenda.
