Of the 27 EU member states, there are two with ALDE-affiliated Prime Ministers: Kristen Michal (Estonian Reform Party) in Estonia and Alexander De Croo (Open VLD) in Belgium.

Charles Michel, former Belgian prime minister, was the president of the European Council until December 2024.

ALDE's think tank is the European Liberal Forum, led by Jan-Christoph Oetjen MEP, and gathers 46 member organisations.

Since then, between 1000 and close to 3000 members (the numbers fluctuate annually) maintained direct membership in the ALDE Party from several EU countries.

Over 40 coordinators mobilised liberal ideas, initiatives and expertise across the continent under the leadership of the steering committee, which was first chaired by Julie Cantalou.

On 26 March 1976, the Federation of Liberal and Democrat Parties in Europe was established in Stuttgart.
