Liz Truss has led tributes to the Queen during a special sitting of parliament saying the late monarch was "devoted to the union".
The Prime Minister insisted Britain must show it does not fear what lies ahead after "our lives changed forever" following the death of its "icon" Queen.
She said the King "bears an awesome responsibility that he now carries for all of us", adding: "Even as he mourns, his sense of duty and service is clear."
