Goldington was the tightest race from the 2015 election, with two Labour candidates now fighting for re-election.
Cllr Anthony Forth came in a comfortable first place four years ago, but fellow Labour member Jade Uko won the other seat by only 16 votes.
The Labour duo have been strong local campaigners, taking a lead on the battle to retain services at Putnoe Walk-In Centre.
However, the Lib Dems have shown their desire to reclaim the seat by putting up Christine McHugh, a former mayoral candidate and wife of the current mayor.
And the Conservatives’ candidates include Phil Merryman who is a former Lib Dem councillor for the ward.
Goldington has previously been safe Lib Dem territory, so the Labour campaign to protect the Walk-In Centre could be the key issue that decides the result.
