Speaking during a state-wide broadcast on Wednesday in Port Harcourt, Wike said that the visit was historic because it was not a political mission.

According to him, the visit is a good omen for the state since it is to kick-start the cleanup of oil exploration-induced pollution on Ogoniland.

``The president is not on a political visit to the state; he is here to kick-start the largest environmental cleanup in our nation’s history; this makes it historic.

``It is a visit for which Rivers people and indeed the Niger Delta will remain grateful.’’

The governor used the medium to urge Rivers people to come out massively to accord the president a warm reception.

``We have, therefore, banned the use of motorcycles and tricycles in Gokana and Khana Local Government Areas for the period between 6 a.m. and 6 p.m. on Thursday.

"I call on Rivers people to be peaceful, law-abiding and demonstrate the traditional Rivers hospitality towards the president and his distinguished entourage throughout the visit.

"As I have noted earlier, Mr President is here as the father of the nation, who cares about the environmental and developmental challenges that we face,’’ Wike said.
