On 30 April the Queen will sign the instrument of abdication in the Royal Palace, Amsterdam. This is the constitutional procedure by which she formally relinquishes the throne. Once the instrument is signed, in other words before the investiture ceremony, the Prince of Orange will become King under constitutional law. He will be King Willem-Alexander. The new King and the former Queen will then give a short address from the balcony of the Palace. The new King and Queen and their three young daughters will then make a public appearance on the balcony.
