The senior Tory politician is no stranger to Parliament as he was MP for Henley for seven years until he left in 2008 to take up the reins at the capital's City Hall.
Following his victory with a 10,000 majority, he said: "It's been a long and exciting evening and obviously I'm very excited by some of the results that are coming through.
"Overall I think it's been an amazing night for the Conservatives."
He told the BBC: "Sad about others, but overall it's been an amazing night for the Conservatives when you consider where we were and what the polls were saying only a few hours ago.
"It's a remarkable turnaround."
He said the "common sense of the British people" meant they "have decided to go forwards, with a sensible long-term economic plan for this country".
With the Conservatives on course to secure the most seats in Parliament, Johnson said: "The people of Britain, after a long and exhausting campaign, have finally spoken. I don't think we need any fancy constitutional expert to tell us what they were trying to say. I think they have decisively rejected any attempt to take this country back to the 1970s, decisively rejected old-fashioned and outdated politics of division, and it is clear to me the people of this country want us to go forward with sensible, moderate policies that this Conservative Party has produced over the last five years and that have led to a sustained economic recovery.
"I think the people of this country want to go forward with that long-term economic plan for the benefit of everybody in this constituency and across the entire country."
Describing himself as a "one-man melting pot" of English, French, Turkish, Muslim, Jewish and German ancestry, Eton-educated Johnson worked as a journalist for the Times and the Daily Telegraph after leaving Oxford University.
