Results showed May was likely to avoid the kind of widespread losses that would dramatically weaken her authority over Conservative lawmakers ahead of key tests of her plans to take Britain out of the EU customs union as it quits the EU.

A major breakthrough deal to fundamentally change China's economic stance was widely viewed as highly unlikely.
