MP David Lammy says he is opposed to further British military action in Syria and will be voting against extending airstrikes.

The Labour MP, who represents Tottenham, says there is “no harder decision” than voting on whether to send British forces to war.

MPs will vote on whether to extend airstrikes against IS targets to Syria after a one-day debate on Wednesday.

But Mr Lammy does not think Prime Minister David Cameron has presented a “compelling” enough case to carry out the strikes and has raised a number of concerns.

In a statement, Mr Lammy said: “I am not an instinctive ideologue or a pacifist on these issues – this, for me, is a matter of conscience.

“If military intervention can help to protect Britain and those who are being persecuted abroad then I am in favour of it.

“However, there must be some guarantee that it will have the desired effect – that is, a reduction in violence and persecution.”

He says he has discussed the matter with his constituents and local party members who agree the Government has not done enough to persuade the country that bombing ISIS in Syria is the correct course of action.

Outlining his concerns, he said there is no long-term plan and as a result, there is no end goal.

He fears air strikes could harm civilians and serve as a key recruitment tool for ISIS.

He added: “We cannot fall into the trap set by terrorists; the attacks in Paris were not just a horrendous terrorist act, but also a provocation.

“I am worried that we are, in effect, taking the bait and performing the acts that ISIS have told their followers around the world would follow.”

He says he is “hugely sceptical” about the Prime Minister’s claim that a Syrian coalition army of 70,000 soldiers are ready to support Western air strikes on the ground because there is no evidence to support this.

He added: “I fear military strikes will deepen the power over the vacuum in Syria that has allowed ISIS to spread its hateful ideology.

“There are already numerous splinter groups and splinters of splinter groups operating in Syria.

“There are no obvious allies in Syria and no guarantee that military action against ISIS will not result in a power struggle between equally unpalatable groups.

“As a result of all of the above, as things stand on Wednesday I will be voting against extending British military action to Syria.”
