Britain says no Iran deal `better than a bad deal`

Vienna: No nuclear deal between Iran and world powers is better than a "bad deal", Britain`s foreign minister said Sunday as he arrived for talks just days before a deadline for an accord.

"We still have very big challenges if we are going to be able to get this deal done," Philip Hammond told reporters. "I have said many times before and I will say it again today, no deal is better than a bad deal."
