Morsi was arrested several times "due to his constantly firm stance against the repressive measures and oppressive practices of the overthrown regime," the party said.
"After the 2005 elections were rigged, Dr. Mohamed Morsi led demonstrations in support for judges demanding independence, refusing referral of some judges to the Competence Commission to punish them for their outspoken views against blatant elections fraud."
The following May, he was among 500 members of the Brotherhood arrested, the party said. Morsi spent seven months behind bars.
"He was arrested, yet again, on the morning of the 'Friday of Anger' on January 28, 2011, during the revolution of January 25 along with a large number of Brotherhood leaders across Egypt. ... When several prisons were destroyed during the revolution, and many prisoners escaped, Dr. Morsi refused to leave his prison cell. Instead, he contacted satellite TV channels and news agencies demanding the judicial authorities visit the prison and check the legal position of jailed Muslim Brotherhood leaders, to clarify if there were indeed any legal reasons for their arrest," the party website says.
