Elected as Deputy for Andenne in 1994 under the banner of the BSU, he quickly rose in prominence within the party and became party leader in the run up to the 1999 election. While failing to lead the party to victory, he secured the BSU's position within the next government and became Deputy Prime Minister and Minister of Finance (1999-2004). He ended up leading the BSU to victory in 2004, with the party gaining a large number of seats.
((The Conservative Progressive Party and the BSU in government together...madness!?))
