Oxford's Randolph Hotel had some special visitors staying overnight.

Former US President Bill Clinton and wife Hillary booked into the hotel, along with daughter Chelsea on November 27, to spend Thanksgiving with student Chelsea, who is studying for a MPhil in international relations at University College, Oxford.

The visit fuelled rumours that Chelsea has become engaged to a fellow Oxford University student.

Asked if her daughter had plans for marriage, Mrs Clinton laughed and would not comment.
