NEW YORK. Oct 21: A spokesperson to the US Democratic presidential candidate Barack Obama said on Tuesday the Senator will suspend his campaign later this week in order to travel to Hawaii to visit his grandmother, who is gravely ill.

Obama’s campaign officials said that Obama is cancelling most campaign events on Thursday and Friday to visit Madelyn Dunham, 86, who helped raise him.

Officials said Dunham’s condition has deteriorated to the point where her situation is serious. She lives in Hawaii. Senator Obama campaigned on Monday in Florida, a populous state in the southeastern US that would give either candidate a significant push towards the White House. On Monday evening, he and Senator Hillary Clinton, his former rival for the Democratic nomination, appeared together in Orlando.—By Our Correspondent
