Donald Trump’s only remaining rival for the Republican Party presidential nomination John Kasich has confirmed his withdrawal from the race. Mr. Kasich,the governor of Ohio, made the announcement at an emotional news conference in his home state. “As I suspend my campaign today, I have renewed faith, deeper faith that the Lord will show me the way forward and fulfill the purpose of my life.” The decision clears the way for Mr. Trump to run for the White House.

Gary O'Donoghue is in Washington.

“Now Donald Trump is the last man standing having swept aside all before him. Once Senator Ted Cruz had decided to bow out after a drubbing in Indiana, John Kasich the Ohio governor had little choice but to follow suit. That makes Mr. Trump the presumptive nominee and he has already called for party unity and said he’ll pick someone with political experience to be his running mates. But some vocal high profile Republicans have vowed not to support him.”

An American lawyer has shed light on the circumstances apparently surrounding the sudden death last month of the pop star Prince. The lawyer William Mauzy told a news conference that the day before the singer died, he’d asked to meet a doctor specializing in addiction treatment. Peter Bolz in Los Angeles has more. “Unable to travel from California to Minneapolis himself, the doctor Howard Kornfeld is said by his lawyer to have sent his son Andrew with drugs to help the singer deal with a painkiller addiction. He also arranged for a local doctor to see Prince. But when Andrew Kornfeld who is not a doctor himself, arrived at the Paisley Park, he was one of three people to find the singer in an unresponsive state. The official cause of death is still not known.”

That was Peter Bolz and that’s the BBC news.
