Former Estonian PM and EU commissioner Siim Kallas lost out to Hans van Baalen in an election to pick the new head of ALDE, EU's main liberal political organization.
Van Baalen received 296 votes to Kallas's 117 on Saturday.
Kallas said his campaign lasted only four weeks, while his opponent began campaigning in May.
Speaking about the Estonian presidential elections, set for August 2016, Kallas said he will accept a nomination. He said currently that is just speculation.
Kallas is one of the early frontrunners, along with Marina Kaljurand, the foreign minister, MEP Indrek Tarand and possibly Edgar Savisaar.
ALDE, the Alliance of Liberals and Democrats in Europe, is a umbrella organization for EU liberal parties. It is also represented in the European Parliament with 70 MEPs and 5 European Commission members, including Estonia's Andrus Ansip. ALDE is the third largest European-wide party in the European Parliament.
