Boris Johnson promised on Thursday that Brexit would make Britain the greatest place on Earth, echoing the patriotic rhetoric of U.S. President Donald Trump in a debut speech as prime minister before Parliament.

Johnson, who was hailed by the U.S. president as Britain's Trump, has promised to strike a new Brexit divorce deal with the European Union and to energize the world's fifth largest economy after what he casts as the gloom of Theresa May's prime ministership.

On entering Downing Street on Wednesday, Johnson set the United Kingdom up for a showdown with the EU by vowing to negotiate a new divorce deal and threatening that if the bloc refused then he would leave without a deal on Oct. 31.
