CAPE TOWN - A former leader of the DA has told eNCA that politics is no place for passive people, especially in the opposition to the ruling party.
Tony Leon said it was normal for strong personalities to clash in the fight for positions. At the weekend, parliamentary leader Lindiwe Mazibuko resigned, saying she wanted to study at Harvard and give politics a break.
Democratic Alliance spokesman Mmusi Maimane is set to fill the post. But Leon says it&39;s a job that party leader Helen Zille should be doing.
