Liberal Democrat councillor Clinton Mead is likely to be elected Campbelltown's new mayor at tonight's council meeting.

Cr Mead, 29, who has served almost a year as a councillor, will replace independent councillor Sue Dobson in the top job.

Former mayor and independent Cr Paul Lake is likely to be elected deputy mayor.

Under a deal between councillors, the Liberal bloc is likely to have the numbers to elect Cr Mead to the position. He will face Labor's nominee, independent Fred Borg, in the mayoral ballot.

The council's Labor leader, Cr Anoulack Chanthivong, said he was pleased Cr Borg would be the Labor ­nominee. "We're fully united behind Fred; he'll be a great mayor," Cr Chanthivong said.

"We signed his nomination form and were delighted to do so," he said.

Liberal leader Cr Paul Hawker said Cr Mead would be the best man for the job and had the unanimous support of his team.

The Camden and Wollondilly Councils will also have Mayoral elections coming up.

Camden Council will also elect a new Mayor tonight, while Wollondilly Council have its election on Monday, September 16.
