Hounslow's Labour MP has said she voted in support of UK air strikes against Islamic State (IS) with a 'heavy heart'.
Feltham & Heston MP Seema Malhotra said it was not an easy decision but ISIL (another name for Islamic State) 'needs to be stopped'.
Mary Macleod, the Conservative MP for Brentford & Isleworth, also supported the motion for UK military strikes on IS in Iraq.
Parliament was recalled to discuss the motion, which MPs have been debating since 10am.
In the vote, held just after 5pm, 524 MPs backed the government motion and 43 were opposed.
The motion commits the UK to air strikes in Iraq on the extremist group responsible for beheading a series of hostages.
However, it states there will be no air strikes on Syria, as it is understood this would breach international law, and no ground troops will be committed in either country.

Seema Malhotra, MP for Feltham & Heston
"This is not an easy debate nor an easy decision. Nobody wants to be part of the process of war. However in ISIL there is no love, no compassion, no element of progress or development. There is only destruction and power, the violation of women and the murder of whole communities whether Christian, Yazidi or Muslim.
"ISIL needs to be stopped. In an ideal world that would be through negotiations. The problem is that the behaviour of ISIL is not subject to negotiation. It is a cancer that will spread as far as the world will allow it. Standing back is not an option if we believe that humanity is worth fighting for and protecting. The action has the support of other Arab states and is directly requested by the Iraqi Government.
"Whilst with a heavy heart I have come to the conclusion that we need to play our part in a coalition to support targeted air strikes, I see no requirement nor appetite for our boots on the ground. This is based on the success so far in stopping ISIL's advance. My concern also is the lack of coherent strategy alongside the international coalition's military action. In Parliament I have called on Ministers to push an active political dialogue, led by Arab nations to put aside differences, genuinely share responsibility for handling the crisis, join up humanitarian support and plan for a sustainable peace. The world needs Arab Nations to lead this campaign for ISIL's defeat. As we move forward, there must be no mission creep and even our limited action must be subject to the closest of scrutiny."
Mary Macleod, MP for Brentford & Isleworth
"I believe ISIL is a real and direct threat to our way of life. It is a disgrace to the free world, especially to the Muslim community here in Britain. I will be voting to support air strikes against ISIL in Iraq today. It is clear that there is cross-party support for action as part of an international effort to push ISIL back and stop their onslaught. It is right that we are united in doing so and it is right that Parliament will be making that decision today."
