John F Kennedy's only grandson has given his first major interview, discussing how Barack Obama inspired him and fielding questions about his own future political ambitions.

Jack Schlossberg, who is about to begin a course at Harvard Law School - Mr Obama's alma mater - spoke alongside his mother, Caroline Kennedy, the former US ambassador to Japan.

In an interview on America's Today programme, the 24-year-old said he admired Mr Obama's commitment to delivering reform on healthcare and climate change.

While he did not mention President Donald Trump by name, an implied criticism was clear.

“That takes political courage," Mr Schlossberg said of Mr Obama's reform efforts.

"And we’re seeing today it’s pretty easy to criticise without offering solutions, and that President Obama did not do that. He had the courage to govern responsibly.”
