Kadima's Director General Yohanan Plesner was sworn in Tuesday as a member of Knesset replacing Shlomo Breznitz who handed in his resignation earlier this morning.

Brezintz, who is considered to be an ally of Prime Minister Ehud Olmert and is 21st on the party's parliamentary list, said he decided to resign in order to focus on academic research.

As a well-known lecturer of psychology, Breznitz founded the Cognifit company in 1998 that develops programs that helps preserve maximal cognitive skills and daily functioning of Alzheimer sufferers.
