Felipe Calderon is a career politician who served as energy secretary under Mexican President Vicente Fox.
Like his father Luis, who helped found the National Action Party, Calderon has been an influential member of the party, serving as its president.
During this year's presidential election campaign, Calderon won the support of Mexico's business leaders. A Harvard-educated lawyer, he has pledged to continue Mr. Fox's conservative economic policies.
He also has pledged to battle crime and attract new investments that would create jobs and help resolve social issues.
During the campaign, he criticized political rival Andres Manuel Lopez Obrador, accusing him of having ties to leftist Venezuelan President Hugo Chavez.
Although election officials banned Calderon's advertisements describing Lopez Obrador as a danger to Mexico, the allegations still dogged his rival.
