Leo Varadkar meets Biden after apparent Clinton-Lewinsky joke

Irish leader meets US president at White House for traditional St Patrick's Day event a day after making gaffe

Ireland's taoiseach, Leo Varadkar, has apologised for making an apparent joke about Bill Clinton's affair with Monica Lewinsky, during an event in Washington on the eve of St Patrick's Day celebrations.

Varadkar's comment on Thursday risked overshadowing his meeting with Joe Biden at the White House on Friday for the traditional handing over of a bowl of shamrock to the US president, the most important day in the Irish-American political calendar.
