MYRA Whiteside was elected to represent the Leigh Central ward on Thursday night in a by-election prompted by the resignation of Kath Thomas earlier this year.
She received 904 votes, the Community Action Party's candidate Peter Solinas polled 392 votes while Timothy Matthews, for the Conservative Party, came third with 149.
This week, Councillor Whiteside spoke about her delight at being elected and her plans for the ward.
She said: "I am absolutely thrilled to bits."
Coun Whiteside – who has worked for the post office for 23 years and is a area representative with the Communications Workers' Union – was put forward to be the Labour candidate after she spoke at a Constituency Labour Party meeting.
Although she had never stood as a councillor before, Mrs Whiteside progressed through the selection process and was picked to be the candidate.
Coun Whiteside said: "My agent, Tom Sherratt, has been really good and has led an excellent campaign.
"I knocked on a lot of doors and produced leaflets, spoke to as many people as I can and it has had a result."
Coun Whiteside has two grown-up children, Colin and Lorraine, and lives in Ashley Street in Leigh with her partner, John Hurst.
Now she has been elected, she is planning to hold meetings with the local community beat police officers as well as council colleagues.
