Babacan announced last July that he was resigning from the AKP over "deep differences" about its direction and his move to establish a new party was seen as potentially eroding support for Erdogan's party.
"We will confirm the party's name at a launch programme on
Wednesday," Babacan said, adding that his supporters would
submit to the Interior Ministry on Monday an official request to
establish the party.
A founding member of the AKP, which has ruled Turkey since 2002, Babacan served as the economic and then foreign minister before becoming deputy prime minister, a role he held from 2009 to 2015.
Economic difficulties in the wake of a 2018 currency crisis ate into Erdogan's support base. Further erosion - even just a few percentage points - would damage the AKP, which already has to rely on an alliance with nationalists for its parliamentary majority.
In December, another one-time close ally of Erdogan, former prime minister Ahmet Davutoglu, established the Future Party to rival the AKP.
