On 19 December 2016, party co-presidents Călin Popescu-Tăriceanu and Daniel Constantin signed an collaboration protocol with the Social Democratic Party (PSD) leader Liviu Dragnea to form a new coalition government with ALDE as the junior partner.

However, during early 2022, ALDE switched to an extra-parliamentary support for the current governing grand coalition which is the National Coalition for Romania (or CNR for short) and is currently negotiating a very probable near future merger with the PNL, but without their former president Călin Popescu-Tăriceanu, who is no longer even a member of the party.
