Nottinghamshire MPs were divided over a Parliamentary vote on bombing Islamic State targets in Syria.
A House of Commons debate ended with backing for the action, by 397 votes to 223.
Prime Minister David Cameron called for Britain to join America, Russia and France in launching air attacks on the terror group’s strongholds.
Labour leader Jeremy Corbyn opposed the action and Nottinghamshire MPs from both parties were split, although a full breakdown of how all members finally voted will not be published until later.
Conservative Newark and Sherwood MP Mark Spencer supported air strikes.
He said: “I believe it makes no sense to bomb Isil-Daesh in Iraq but to let them operate unhindered in Syria, from where they can plan and launch attacks.
“I do not agree with the argument that bombing them in Syria will make the UK more of a target; we are already very much a target, as the seven foiled terror plots against the UK in 2015 show.”
But Labour’s Nottingham South MP Lilian Greenwood said she was opposed, saying there is not enough proof anti-terror fighters in Syria can take control if IS is driven back.
In a Facebook post, she said: “Their capacity to fill the void that ISIS would leave has not been proven, in my view, and the eventual scope of British intervention is therefore unclear.
“As I have not been convinced, I have concluded that I must vote against the motion.”

Nottingham North MP Graham Allen, also Labour, is also against strikes, saying there is no convincing plan about what to do in Syria beyond military action.
He said: “We need a fully-fledged multi-dimensional strategy, not least to fill the institutional vacuum should Islamic State be pushed back militarily.
“The question “What are the plans to win peace, should we win the war?” remains unanswered.”
The RAF was already targeting IS in Iraq, but its heartland is considered to be in Syria.
The extended air strikes were proposed after IS militants killed 130 people in gun and bomb attacks in Paris last month.
All I can do is try my best
Nottingham East MP Chris Leslie wrote to constituents, asking for their views before he decided how to vote.
“I am committed to a regular ongoing dialogue as I try to keep an open-mind to the evidence, the arguments and alternative points of view,” he said.
“All I can do is try my best to be guided by what I judge to be in the best interests of all my constituents.”
