In a statement in Abuja, Senator Mark cautioned PDP leaders against imposition of candidates.
He urged all members of the party to conduct themselves peacefully with a view to ensuring respect for law and order.
“As we converge to elect delegates to the Congresses beginning from Saturday, we must be guided by democratic tenets and observe the principle of fairness and justice,” Mark said in the statement signed by his media aide, Mr. Paul Mumeh.
He added: “We must demonstrate to fellow country men and women that we are truly democratic.
“I am sure that our members nationwide will showcase our reformed and rebranded party as the preferred choice for the people.”
Senator Mark said he joined the presidential race because “I believe I can make a positive difference in Nigeria.”
Continuing, he said: “nobody can shy away from the fact that Nigeria is currently faced with intractable security, economic and socio-political challenges that unarguably threatens the corporality of the country.
“Rarely has our country been faced with such a state of uncertainty, despair, suspicion and division.
“The time has come for all men and women who care and have the requisite experiences and courage to stand up, retrieve it from the brink and lead our nation into prosperity.”
Senator Mark expressed optimism that his roadmap to economic recovery and prosperity tagged ‘730 model’ will turn around the economy of the nation within two years of his administration if he is elected President.
He said he has assembled a team of young professionals who can hit the ground running and facilitate the economic recovery.
He also pledged to give education top priority as the bedrock for development.
His words:”We will focus on education and create a pool of highly trained citizens with excellent IT skills who will be employable as well as create jobs.”
“We will support Small and Medium Scale Enterprises (SMEs) as a matter of priority with interest free cooperative loans and appropriate technology, which will be the main driver of the economy with attendant rate of huge employment opportunities.”
