Johnson told his cheering audience that he wanted the United Kingdom to "recover its self confidence" and "stand tall in the world" while he said his party would "get Brexit done" and then deliver on its election promise to invest more in hospitals, schools and police.
According to the latest figures, the conservatives get 364 seats in the 650-strong lower chamber, labour - 203, the Scottish national party - 48 seats, liberal Democrats 11. "Mr Johnson commands a majority, but there is a palpable sense of fear amongst Muslim communities around the country", said MCB secretary general Harun Khan in a statement released on Friday.
On Saturday, he promised to build "a one-nation Conservative government, a people's government" that will increase funding for health services, policing and infrastructure.
"I urge everyone to find closure and to let the healing begin", Johnson said hours after visiting Queen Elizabeth II to be reappointed prime minister. "We are going to get Brexit done".
Asked whether he had interest in a leadership role, he said he wanted to "play my part in rebuilding the Labour Party.to win an election again".
This announcement came after Johnson's historic election win on Thursday, which secured the biggest Conservative Party majority since the 1980's. The election campaign had seen a large number of blows and counter-blows exchanged between both the Johnson-led Tories and Jeremy Corbyn-led Labour Party over their record on minorities.
Passage of the deal, which allows Britain to withdraw from the European Union on January 31, is expected to be a formality after the Conservatives won a big majority in the election.
President Trump has previously given his backing to Johnson, telling reporters in November this year that he was the "right man for the time" and a "great gentleman".
A Northern Ireland-born Labour MP has said poor leadership of his party left it without a connection to working class people, leading to its worst general election result in decades.
