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.
