Megyn Kelly has exploded back onto US television screens, returning after a four month hiatus with an exclusive interview with Vladimir Putin.

Kelly, 46, was one of Fox News’ highest-profile anchors, famously feuding with Donald Trump, until her shock departure in January.

On Thursday she announced her return to television with a preview of her new Sunday night show on NBC, in which she will interview the Russian president.

Kelly told her new NBC colleagues that she was in St Petersburg to chair a discussion at the annual International Economic Forum.

“As part of the forum, President Putin will be taking part in a panel and I'm lucky enough to be asked to moderate that,” she said.
