Semjén spoke to journalists after a meeting with EPP president Manfred Weber in Budapest on Friday, hirado.hu reported.

Magyar or Tisza joining the EPP group would be unacceptable for KDNP, Semjén, who is also deputy prime minister, said.

He added that the KDNP has an 80-year history, while the Tisza party has been around for 80 days.

In the recent EP elections, the governing Fidesz-KDNP coalition won 11 mandates, while newcomer Tisza took seven.
