UK 'could join US strikes on Syria' - Johnson
Suggests any action may not get MPs approval first
Britain could join a US strike on Syria if a request was made by Washington, Foreign secretary Boris Johnson said on Thursday.
He added that parliament might not get a vote on the matter.
"I think it would be very difficult if the US has a proposal to have some sort of action in response to a chemical weapons attack,” he told the BBC.
"And if they come to us and ask for our support - whether it's with submarine-based cruise missiles in the Med... in my view - and I know it's also the view of the prime minister - it would be difficult for us to say 'no'."
He said the usual convention by which MPs normally voted on any military action needed to be “tested”.
Earlier this month the US carried out a missile strike against a Syrian air base just days after a chemical attack it claimed was carried out by forces loyal to the country's President Bashar al-Assad.
The chemical attack left 80 people dead and hundreds wounded. The regime has denied involvement.
