US Senate Republican leader Mitch McConnell to step down in November

The Republican leader of the US Senate, Mitch McConnell is to stand down in November, AP is reporting.

It ends a record run in the powerful post, that has seen the 82-year-old trade blows with many top figures in multiple US administrations of the last two decades.

In a prepared statement obtained by the news agency, Mr McConnell said: "One of life's most underappreciated talents is to know when it's time to move on to life's next chapter.

"So I stand before you today... to say that this will be my last term as Republican leader of the Senate."

Despite relinquishing the position of Senate leader, Mr McConnell intends to see out his term in the US' upper house, which ends in January 2027.

Questions were raised about his fitness for office last year after a number of public instances where he appeared to freeze.

In July, the Republican appeared to freeze mid-sentence and stare into space for around 20 seconds while giving a weekly press conference.

His Republican colleagues grabbed his elbows and asked if he wanted to go back to his office after pausing for around half a minute, before he slowly walked back to his office with an aide and the senator for Wyoming, John Barrasso.

Then, in August, Mr McConnell appeared to freeze again when asked if he would run for re-election.

After being asked, he stopped speaking and stared for more than 30 seconds, before being asked: "Did you hear the question, senator?"

He did come around and briefly respond to another question.
