The four powerful Nigerian Amazons

1. Ngozi Okonjo Iweala

Number one in OBJ list, she is perhaps the only one that hasn't been tainted with corruption, long may it last. The former Managing Director of World Bank (October 2007–July 2011) and now Minister of finance with a fancy title "coordinating minister of the economy" was born in Delta State, she married an Abia man that hails from Umuda Isingwu in Umuahia North LGA of Abia state. On September 2012 she became one of three candidates in the race to replace World Bank President Robert Zoellickat the end of his term of office in June 2012, though she lost this further cemented her position as the most powerful woman in Nigeria.

2. Dame Patience Goodluck Jonathan

Nigeria's current firstlady and wife of President GEJ, she is famous for adding some pidgin sentences to the Nigerian Pidgin vocabulary. She invented the "na only you waka come" and " there is God o!" which are favourite pharases amongst Nigerians. The former Bayelsa firstlady comfirmed her place as the number two powerful woman in Nigeria by helping her husband become president.

3. Deziani Alison Madueke

She comes at a distant number 3. Her popularity has more to do with connection, she married Allison Madueke (retired), one-time Chief of Naval Staff who was at various times governor of Imo and Anambra State, currently she is the Minister of Petroleum (Nigeria's own black gold), by virtue of this, she is the head of almost 90% of money that comes into the country. The Port Harcourt born lady is even more powerful now that she is made the first Female President Of Gas Exporting Countries (OPEC).

4. Stella Oduah

Who would forget the huge money this woman spent in buying two bulletproof cars for her protection? Her 'strong woman' character was seen when she compelled the Nigerian Civil Aviation Authority (NCAA) to pay Coscharis Motors, an auto dealer, approximately $1.6 million for two BMW bullet-proof cars. Investigations by us showed that the highest cost for each such car in both the US and UK was $267,000 per car. NCAA and other sources further disclosed that the two cars were never delivered, compounding a scam by Ms. Oduah who reportedly split the $1.6 million funds with Cosmas Maduka, the chief executive of Coscharis. Highlighting how strong she is, she wasn't prosecuted, she just resigned from office with her $1.6 million funds intact.
