Perikatan Nasional (PN) information chief Azmin Ali wants Umno back at the negotiating table to discuss the party's traditional seats that it originally won in the 14th general election (GE14).
The issue is said to have affected the relationship between Umno and Bersatu after 13 constituencies Umno won in GE14 fell to Bersatu due to defections.
BN had previously warned that it would defend all its traditional seats whether it won them in GE14 or through by-elections.
