Photographs dating back more than a decade of Donald Trump, the Republicans’ presumptive candidate for the White House, and Bill Clinton are to be released.

With the mogul bracing himself to fight Hillary Clinton for the presidency in November, the release of the pictures will show how close he once was to the former First Family.

In recent weeks Mr Trump’s attacks on the Clintons have become more personal, calling her “Crooked Hillary” and raising past sexual abuse allegations against the former president.

Some observers believe the release of the photographs could undermine the Trump offensive on the Clintons.
