SDE chairman Lauri Läänemets wrote on social media that Siim Kallas was a good leader. He always knew what he wanted. He stood up for his opinion. This is important for a politician. People recognize this. Competitors respect it. Kallas was an extraordinary man. He made Estonia better.
Läänemets said they had different worldviews. But this did not hinder cooperation. Kallas could speak directly but remained polite. He was internally firm but open to others.
Isamaa chairman Urmas Reinsalu praised Kallas. He said Kallas was an influential leader. His influence will remain in Estonia for a long time. Conversations with him were profound. He was generous and polite even in disputes.
The Center Party's Janek Mäggi wrote that Kallas was a diligent and persistent man. He learned a lot from him. Kallas read many books. Mäggi found it hard to keep pace with him. Kallas said that we can choose how we live. He chose a life full of joy.
The Right-wingers' Ilmar Raag called Kallas a great man. He learned to respect him. Some didn't like his moustache or economic views. Raag did not trust politicians, but Kallas changed his mind. He was educated and patriotic. He belonged to the generation of intellectuals.
