British Prime Minister Boris Johnson has banned ministers from attending the World Economic Forum for the global elite in Davos next week, according to a Downing Street source. 

Boris Johnson lead his Conservative party last month to its biggest election win since Margaret Thatcher's landslide victory of 1987.

He pledged to run a "people's government" that would deliver Brexit and repay the trust placed in him by voters in former strongholds of his Labour opponents.

"Our focus is on delivering for the people, not champagne with billionaires," the source said, referring to the annual gathering in the Swiss ski resort of politicians, business leaders and celebrities. 

The move echoes US President Donald Trump, who banned senior officials from attending Davos in 2017 shortly after he took office. Donald Trump is attending Davos this year, however.

The 2020 event will be held from January 21 to 24.
