This is from his speech at the 2003 National Day, after the vote to change the consitution.
"The missions in foreign and home affairs for which I have fought, are or closed or are about to be closed successfully. New missions must be solved, with which the hereditary prince has already been kept busy with intensively. With that for me slowly has come the time to withdraw from political life. Next to that we, in the princely house, are already long of opinion that the Fürst (Prince) hands over the political powers to his heir when this one is willing to take over.
So has my grandfather renounced in favour of my father, and has my father handed over political powers to me when I had largely closed the reorganisation and the reconstruction of the Princely Finances. The Hereditary Prince and I have decided that the delegation of political powers will take place in one year at the next Staatsfeiertag (national day)."
