Q: Sen. Bob Corker (R-TN)  speaks with reporters after announcing  his  retirement at the conclusion of  his  term on Capitol Hill in Washington  U.S.  September 26  2017. REUTERS/Aaron P. Bernstein
WASHINGTON (Reuters)  - U.S. Senator Bob Corker   the influential Republican chairman of the Senate Foreign Relations Committee  said on Tuesday he will not run for re-election  a blow to a party already struggling to balance divisions between mainstream and more populist wings.
An establishment Republican   Corker  has been criticized from the right  and a conservative activist had already announced a primary challenge. But he was expected to keep the seat  and had amassed a $7.5 million campaign war chest.
 Corker  has ruled out running for governor of Tennessee.
âI have no idea what Iâm going to do. No idea whatsoever â  Corker  said in an interview. But he said he was not leaving out of frustration over deep party divides that have often paralyzed Congress.
 Corker  announced  his  retirement on the day of the failure of the latest Republican effort to repeal former Democratic President Barack Obamaâs healthcare law.
âI am not going to be one of the people who leaves here badmouthing what is one of the greatest privileges of oneâs life â  Corker  said.
He said he realized he was ready to retire on Aug. 24 during a factory groundbreaking in Clarksville  Tennessee  and almost announced his decision at least twice before Tuesday.  Corker  said that he made his announcement now to allow a strong candidate time to enter the Senate race.
 Corker  is the first senator to announce  his  retirement ahead of the 2018 mid-term elections  when one-third of the 100-seat chamber will be up for grabs. Tennessee is a solidly Republican state and the party  which currently holds a 52-seat majority in the Senate  is favored to keep his seat.
In his official announcement   Corker  said that âafter much thought  consideration and family discussionâ over the past year  he and his wife Elizabeth âhave decided that I will leave the United States Senate when my term expires at the end of 2018.â

CLASHES WITH  TRUMP
In August  after Trumpâs much-criticized reaction to violence at a white supremacist rally in Virginia   Corker  told reporters in  his  home state Tennessee that Trump had not been able to demonstrate the âstabilityâ or competence that  he  needed to be successful as president.
After the exchange  the two men had an hour-long meeting at the White House this month that  Corker  has described as a wide-ranging and friendly discussion.
 Corker  will remain chairman of the Foreign Relations Committee until he leaves in January 2019. He said he wanted the panel to address issues including Secretary of State Rex Tillersonâs State Department reorganization  food aid reform  and the fight against human trafficking and modern slavery.
 Corker  said the committee would address the international nuclear agreement with Iran  as Trump faces a mid-October deadline for deciding whether to certify that Tehran is complying with that pact. That decision could force Congress to decide whether to reimpose sanctions.  Corker  would not say whether Trump had decided to certify or not.

Q: Over a span of several months  71-year-old President Mamadou Tandja has imposed rule by decree  cracked down on opponents and the press  and dismantled parliament and the constitutional court  which oppose his plan and together represented the last real checks on his rule.
 On Tuesday  a controversial referendum could remove the last obstacle in Tandja's way -- the constitution -- replacing it with a new one that does away with term-limits and simultaneously gives him greatly boosted powers and an unprecedented three-year extension of his rule.
 "He took the oath of office swearing on the Quran to protect our nation's democratic institutions " opposition leader Mahamadou Issoufou said. "But instead  he is destroying them."
 Opponents say Tandja is clinging to power so his family  clan and entourage can benefit from an influx of wealth from large-scale projects that are under way. Tandja denies it and says he is only obeying the will of his people  who he feels want him to finish projects to develop one of the poorest nations in the world.
 "The people see the future and they are asking their president to continue to serve  so he completes this work " Tandja told The Associated Press in an interview Friday at his residence  a complex of low-rise sand-brown buildings surrounded by palm trees. "But the constitution does not permit me to stay ... that's why the people demand a new one. We need to find a way."
 "It's an existential problem for many African heads of state " said Mahamane Ousmane  who led parliament until Tandja dissolved it in May because lawmakers opposed the referendum. "They can't imagine a normal life outside the palace. They say  'Will I be in exile? Will I be in prison? What will I do?'"
 Ousmane defeated Tandja in a 1993 poll and served as president until he was toppled in a 1996 coup. Today he lives in a modest home on a dirt road in the sleepy capital.
 Tandja  however  told The AP he was "afraid of nothing."
 Any influence foreign donors may have has been undermined by several huge new projects that have buoyed Tandja and are unlikely to grind to a halt. Among them: a US$5 billion (euro3.5 billion) deal with China to build an oil refinery and extract new crude from the desert  a US$1.7 billion (euro1.2 billion) accord with French nuclear giant Areva to build the world's second biggest uranium mine and a hydroelectric dam financed with US$50 million (euro35 million) from the Islamic Development Bank.
 Tandja claims his actions are legal  but opponents say he could only rule by decree if Niger was under threat and parliament was in place to safeguard against abuse. Tandja dissolved the constitutional court -- the only body that could judge such disputes -- after it ruled the referendum illegal. He then replaced it with another court whose members he appointed.
 The proposed new constitution would give him authority to name one third of a new 60-seat senate and the power to jail journalists who are deemed security threats without warning.
 A roadside florist  Hama Alhassane  hasn't seen the draft constitution and doesn't know how it differs from the current one. But "whatever Tandja wants  I will do " the 23-year-old said. "Because he is the state and we must do what the state demands."
 State media only carry pro-referendum messages. A private TV station that broadcast a statement critical of Tandja was temporarily shut down.
 Tandja vowed to respect the outcome  telling The AP: "If they say no  I will go."
