Democratic presidential hopeful Hillary Clinton has ruled out a cabinet position for her husband if she wins the White House in November’s election.

During a campaign stop at a diner in Paducah, Kentucky, the former Secretary of State mouthed “No” when asked if former President Bill Clinton would be a key member of her administration.

A day earlier Mrs Clinton had said that should she become the first US female president: “I expect him to get to work.”

Speaking at a rally in Covington, Kentucky, on Sunday, Mrs Clinton said she planned to put Mr Clinton “in charge of revitalising the economy”.

“He knows how to do it,” she said, adding: “And especially in places like coal country and inner cities and other parts of our country that have really been left out.”

Clinton spokesman Nick Merrill told reporters that Mrs Clinton had not decided what her husband’s specific role would be if she were elected.

Earlier this month, Mrs Clinton said she would want the former president to “come out of retirement” to play a role in her administration.

Mrs Clinton is campaigning in Kentucky on the eve of primaries in the southern state and in Oregon on the West Coast.

She is facing a resilient challenge from Vermont Senator Bernie Sanders for the Democratic White House nomination.The Clinton camp is eager to focus on a likely battle with presumptive Republican nominee Donald Trump.
