The son of an Irgun member who fought during Israel’s war of independence has been elected the first Jewish mayor of Chicago.

Rahm Emanuel, former chief of staff to President Barack Obama, will succeed the city’s incumbent mayor Richard Daley after winning 55 per cent of the vote.

It was a solid victory for the native Chicagoan, despite a campaign marred by a legal challenge to his candidacy.

Mr Emanuel, 51, who also worked as a senior adviser to President Bill Clinton, described his victory as humbling.

Addressing his supporters at a victory rally, the famously highly-strung politician said: "You sure know how to make a guy feel at home.

"Tonight we are moving forward in the only way we truly can. Together. As one city with one future.

"I am determined with your help to meet our challenges head on and to make a great city even greater."

President Obama said of his former aide’s win: "As a Chicagoan and a friend, I couldn't be prouder. Rahm will be a terrific mayor for all the people of Chicago."
