DERBY North MP Chris Williamson said that the views of our readers "weighed heavily on his mind" as he voted yes to war with Islamic State.
The UK Parliament today backed British participation in air strikes against Islamic State extremists in Iraq.
And the final result of the Derby Telegraph's poll, 68% for and 32% against, suggests that the majority of the city was behind them.
But there was not a clean sweep of our local MPs voting yes, with Amber Valley Tory Nigel Mills among the 43 who voted against.
There were 524 votes for, including Derbyshire's Mr Williamson, Dame Margaret Beckett, Heather Wheeler, Patrick McLoughlin and Pauline Latham.
Conservative Erewash MP Jessica Lee was unavailable to comment.
The Government's motion was for air strikes on Iraq and not bombing of Syria or the sending-in of ground troops.
Mr Williamson said he had been "conflicted all day" about the decision. He said: "I spoke to Ed Miliband and [Shadow Secretary of State for Defence] Vernon Coaker before the vote and both of them urged me to support the Government.
"But I still still have worries about mission creep, and whether this is going to make matters worse or better.
"The poll results certainly weighed heavily on my mind when making the final decision.
"In recent days, the majority of members of the public who contacted me directly were against going to war, but taking the poll results into account, the total was more like 60% yes and 40% no."
Islamic State is a terrorist group made up of extremists from the Sunni branch of Islam that has taken over large parts of Iraq and Syria, leaving a trail of murder and destruction in their wake.
Its sights are set on controlling of all the world's Muslim regions and David Cameron has previously warned that it is planning attacks on the UK.
Mr Mills said he voted no because the Iraq air strike plan "didn't have any realistic proposal of success".
He said: "I don't think anyone really believes air strikes on Iraq will fix the problem."
Mr Mills said he couldn't see any way that a successful campaign wouldn't eventually involve an attack on Syria, over which there is no political consensus.
And he added: "There's an acceptance in the debate that there will need to be troops on the ground to fix this and the hope is that the Iraqi and Kurdish armies will be able to do the job. But there's no signs of that at this stage.
"The Government set out that this is not likely to be a short-term operation and it may last three years, which looks implausibly long for air-strikes alone.
"This looks like the thin end of the wedge that will inexorably lead to more action in Iraq and Syria – even though neither is contemplated by today's vote."
Mr Mills said the key would be for the Iraqi Government to have the support of both Shia and Sunni Mulisms, Christians and Kurds, and not be a "sectarian Shiite state".
Mid Derbyshire Conservative Pauline Latham said the turning point for her in voting yes was a letter she received from a constituent in Dale Abbey.
She said: "It's the first time I've ever had to make a decision like this and I was extremely concerned about it as it's not something anyone takes lightly.
"I had a letter from a constituent whose neighbour had an e-mail from a Christian missionary working out there.
"It said that Islamic State are going from Christian household to Christian household and saying 'do you denounce Jesus'.
"When they didn't say yes they were beheaded. In my view that is barbaric. They just don't seem to care."
Derby South's Labour MP Dame Margaret Beckett said her concern was that, thanks to its military success so far, and the money it has been able to steal, Islamic State has a considerable arsenal.
She said: "Unless they are dealt with, they have the capacity to sweep right across nations, spreading mayhem and devastation wherever they go."
South Derbyshire's Conservative Heather Wheeler said she voted yes because the Iraqi Government had invited the UK to help, and the level of brutality Islamic State was using against Christians, Yazidis and other minority groups.
During yesterday's seven-hour debate in the House of Commons, Prime Minister David Cameron said intervention at the request of the Iraqi government was "morally justified" to combat a "brutal terrorist organisation" and was clearly lawful.
He won support from Labour leader Ed Miliband who said inaction would lead to "more killing" in Iraq.
But Shadow Education Minister Rushanara Ali, MP for Bethnal Green and Bow, resigned from Labour's front bench in order to abstain in the vote.
The US began a series of air strikes in Iraq last month and on Monday it began attacks on targets in Syria.
Jets from Saudi Arabia and the United Arab Emirates have joined US forces in the attacks, and the US says more than 40 countries have offered to join the anti-IS coalition.
The government has said it would seek separate Parliamentary approval for the extension of air strikes to Syria but reserved the right to act without consulting MPs in the event of a humanitarian emergency.
Islamic State, also known as Islamic State of Iraq and Levant, describes all non-Sunnis as heretics.
On September 13, it released a video which it said showed the beheading of UK aid worker David Haines.
Islamic State have also threatened to behead fellow UK aid worker Alan Henning.
