Watch live:MPs Debate bombing ISIL in Syria
Defense Secretary Michael Fallon said on Wednesday that it was "illogical" that Royal Air Force jets only conduct airstrikes against Islamic State extremists in Iraq, because the militants "don`t differentiate between Syria and Iraq."
ut lawmaker Crispin Blunt, chairman of parliament`s Foreign Affairs Committee, said British strikes in Syria would make "no practical difference" to the US-led military campaign.
In September, MPs voted to attack militants in Iraq, but not Syria.
No vote on expanding the strikes to Syria is currently scheduled.
Watch Mr Fallon`s statement to lawmakers live here today from approximately 12pm.
