Talk show host Larry King in hospital with Covid-19 for more than a week

Veteran talk show host Larry King has been hospitalised with Covid-19, US media has reported.

Citing a "source close to the family", CNN reported that King, one of the network's biggest stars, has been hospitalised for more than a week at Cedars Sinai Medical Center in Los Angeles.

King, 87, has Type 2 diabetes and has had a long history of medical issues, including several heart attacks, lung cancer and angina, a condition caused by reduced blood flow to the heart.

The legendary host is one of the most recognisable figures on US television, known for his signature rolled-up shirtsleeves, multi-coloured ties, suspenders and big glasses.

His list of interviewees has ranged from every US president since 1974 to world leaders Yasser Arafat and Vladimir Putin, and celebrities Frank Sinatra, Marlon Brando and Barbra Streisand.

King hosted CNN's "Larry King Live" for 25 years, retiring in 2010. He continued to do interviews on his own website and then, in 2012, he began hosting "Larry King Now" on Ora TV, an on-demand digital network that he co-founded.

In 2013, he also began hosting a show called "Politicking with Larry King" on Ora TV.
