Downing Street said it has "not ruled out" recalling Parliament to discuss military action in Syria but added it could need to "take action very swiftly" in the Middle East.
After Labour urged David Cameron to consult MPs ahead of any decision on Syria, a No. 10 spokesman said:
The Prime Minister has made clear that MPs should have the opportunity to debate issues like this and that still stands although we must reserve the ability to take action very swiftly if needed.
No decisions have been taken on military action and the timetable for a serious response from the international community is not yet clear. We are very conscious of when MPs are due to return and haven't ruled out recalling them earlier.
