Mark, in a condolence message, said that Dr Agagu was a trust worthy and mature politician who played politics without bitterness.
In a statement signed by his Special Adviser on Media, Mr Kola Ologbondiyan, Mark noted that the deceased neither pretended nor shied away from saying the truth no matter whose Ox was gored.
“As a minister, Agagu distinguished himself as a goal-getter. As the then executive governor of Ondo, he recorded impressive outing as a performing governor.
“As a political leader he gave his people a sense of belonging,” Mark said.
The senate president pointed out that Agagu would be remembered as a political leader who brought his people into the mainstream politics of Nigeria without compromising their interests.
He sympathised with the government and people of Ondo, especially the bereaved family, saying that Nigeria had lost one of her best politicians.
