In a detailed statement Mr Scully has outlined his views.
The full statement can be seen at VOTE
He starts his statement in the following way:
"Committing our Armed Forces to conflict is one of the hardest decisions that Members of Parliament have to make. I don’t think anyone approves such a move lightly. Civilian lives and those of our servicemen and women have to be at the forefront of our thoughts along with our security here in the UK. I am of the opinion that we have to take the fight to ISIS/Daesh. Therefore I will be supporting a vote for air strikes in Syria but it is only right that I explain my reasons. This is a complex issue to which a short paragraph or sound-bite would do no justice. "
