LONDON - British Prime Minister Boris Johnson's government will on Thursday (Aug 1) face its first electoral test as voters in a rural constituency in the heart of Wales in the north-west part of the country cast their ballots for a new MP.

If the constituency - until recently held by Mr Johnson's Conservatives - goes to the opposition, that will complicate even further the British government's ability to govern, since his majority will be down to just one seat, and he already lacks an overall control over the Parliament in London.
