Contreras is currently second in the Line of succession to Prime minister Dean Barrow who will retire as Prime minister on 1 April 2020 behind Deputy prime minister, Patrick Faber. He belongs to the UDP. In addition, Barrow has also decided not to seek another term in his Queen’s Square constituency and will officially resign from Electoral politics on 2 November 2020, once the results for the 2020 general election is out. On 7 February 2006, Barrow told 7 News that he will resign if the UDP losses the upcoming Municipal elections. Contreras was at that time one of the two choices who would succeed Barrow as Leader of the UDP, if he were to resign then. The other choice was Shadow Minister of Police and the Army, Michael Finnegan. After the UDP won the 2006 municipal election, Barrow kept his promise and remained as UDP Leader.
