AMK presented its central committee line-up today and reiterated their challenge to their Umno counterparts for a debate over Pakatan's proposed 100-day plan dubbed the 'Orange Book'. <br /> <br />"As of now our letter to them remains unanswered. If they do not answer, we can only assume no one in Umno dares to debate with us over this matter. <br /> <br />We delivered a formal letter and we expect them to reply to us formally, not on Twitter," said its chief Shamsul Iskandar Md Akin today.
