A by-election will be held in Broadheath in May after councillor Louise Dagnall stepped down due to ill health.
Dagnall has represented the ward since regaining it for Labour at the local elections in May 2014.
Andrew Western, leader of Trafford Labour Group, said Dagnall’s decision had been taken following a “period of ill health”.
A by-election will now be held on May 4th at the same time Trafford residents will be voting to elect a new Greater Manchester Mayor, with council leader Sean Anstee in the running.
Trafford Council said registered voters in the Broadheath ward will be notified of this formally on their poll cards and will be given two papers to vote on the day.
Anyone not registered to vote must register before Thursday April 13th.
Chief Executive of Trafford Council and Returning Officer for the Borough, Theresa Grant, said: “Voting for the Mayor of Greater Manchester is really important. The role will direct services that matter to you on a very local level and I encourage as many voters as possible to come out and vote on 4th May 2017 for the candidate that represents them the best.
“Likewise, residents living in Broadheath should take the opportunity to vote in the by-election, a local councillor plays a very important role in representing the views of local people.”
The Notice of Election will be published at 4pm on Friday 24 March and nominations to stand as a candidate in the Broadheath by-election will be accepted between 9.30am and 4pm from Tuesday, 28 March until 4pm on Tuesday 4 April at the Town Hall. Appointments for an informal check of papers and to submit nominations can be made by emailing firstname.lastname@example.org.
