Both Siobhain McDonagh and Stephen Hammond will be voting "yes" to extending military air strikes against Islamic State in Syria today. 

The vote, which is due to take place at 10pm following a 10 hour debate in the House of Commons, will decide whether the UK will join other countries including France, the US and Russia in bombing Isis strongholds around Syria.

Labour MP for Mitcham and Morden, Ms McDonagh, will be voting against the stance of Labour leader Jeremy Corbyn, who only agreed at the start of the week to allow his MP’s to have a free vote on the issue. 

In a statement, Ms McDonagh acknowledged public concerns about the outcome of further military action, but argued that Isis "pose a direct threat to our national security". 

She said: "Having given the matter serious thought, and used the evidence presented and my own conscience as my guide, my intention is to vote in favour of the intervention outlined, alongside renewed diplomatic efforts to resolve the humanitarian crisis in a way that reduces the unimaginable human suffering in Syria. 

"Only through agreed international action can we bring an end to the civil war in Syria and thus tackle the refugee crisis and the evil of terrorism. 

"This has not been an easy conclusion to come to, but I truly believe that it is the right one."

Some Twitter users have expressed disappointment with Ms McDonagh's decision, but others have supported her stance.

Conservative MP for Wimbledon, Mr Hammond, will also be voting with the government in favour of air strikes later today. 

In a statement, he paid tribute to the victims of the Paris attacks on Friday, November 13, and described Isis as "an evil death cult who, as these events show, are a real risk to us in the United Kingdom."

He said: "I believe we should join the international community by taking all steps to destroy Isis, to stop the spread of their ideology and to protect our citizens, and so I will be voting in favour of the motion tonight.

"However, military action is only one part of our fight against Isis. We must ensure that there is a full commitment to supporting and rebuilding the areas currently controlled by Isis, more action on curtailing their funding, and to continue our humanitarian support for refugees in the Middle East. 

"To me this shows we are learning the lessons from the past, particularly our interventions in Iraq and Libya. This is important, as whilst we must learn from and rectify our errors, we cannot let these mistakes force us into inaction when British civilians are at risk."

He added: "I would like to thank all constituents who have got in touch with me on this issue. I have thought very seriously about this vote, and I hope even if you do not agree with my decision, you understand my reasons."

Air strikes against Isis would be legal, after the United Nations passed Security Council Resolution 2249 which called on all countries to take "all necessary measures" to prevent further terrorist attacks and "eradicate the safe haven they have established over significant parts of Iraq and Syria."

The motion proposed by the government would authorise air strikes exclusively against Isis in Syria, and does not include sending in troops. 

It also highlights the importance of providing humanitarian support to refugees, and "acknowledges the importance of seeking to avoid civilian casualties".
