Is Liverpool Mayor Joe Anderson right to break weekly bin collection pledge, or is Green John Coyne for sticking to the promise?
Mayor Anderson included the unequivocal pledge on page 10 of his manifesto: "I promise to keep weekly bin collections."
John Coyne made a similar pledge when he sought re-election to the council in 2011.
Next week the council will vote to dump weekly bin collections for 63% of households, on the recommendation of Mayor Anderson.
Terraced streets will be exempted from the changes.
It is clear the mayor's election pledge will be broken with the introduction of alternate weekly collections (where general waste collected one week and recycling the next).
Mayor Anderson's report recommending the change outlines the issue: Officials believe the change would help increase the city's woeful recycling rate of 26% by 10%.
It would save the council between £6.2m and £11.1m in little over two years because of reduced collection costs and savings in landfill tax.
Cllr Coyne says he will not vote to move to alternate weekly collections.
"Personally I don't think I can support going back for the remaining term of my office until 2015.
"For me it's not so much about the bins but how democracy should work."
What is a Green politician doing pledging not to introduce fortnightly bin collections when all the evidence points to the fact it leads to massive improvements in recycling?
And what was Mayor Anderson doing pledging to keep weekly bin collections when he knew very well the council would continue to get hammered by government cuts?
And crucially who of the two of them is right? And does the public even expect election promises to be kept by politicians?
Cllr Steve Munby, cabinet member with responsibility for recycling, sums up the council's position as such: "I think the measures that have been taken in the past clearly have not delivered the step change that was needed.
"The long term financial position is making us ask questions that we might not have wished to have ask.
"I think if you had asked officials or politicians a year ago whether we would be doing this they would have said 'no'.
"But only a fool does not change their mind when the circumstances change."
Have circumstances really changed? Landfill tax has been going up by £8 a year, per tonne, for some time now. And councils have a target of hitting a 50% recycling rate.
Cllr Munby is right that circumstances had changed in one key aspect. The topic of bin collections used to be a toxic topic in Liverpool politics and elections.
But there is now a virtually consensus behind adopting fortnightly bin collections, and given the huge savings it will deliver and the improvements in recycling why not do it now?
But I'll finish with my earlier question who is right: Joe Anderson for breaking his pledge (even if there are very good reasons for doing so), or John Coyne for sticking to a promise he made (despite the fact it flies in the face of what his party stands for)?
