MOSCOW (Reuters) - Russian opposition leader Alexei Navalny was barred on Monday from running in next year’s presidential election after officials ruled he was ineligible to take part due to a suspended prison sentence he says was trumped up.
The decision by the central election commission was widely expected as election officials had repeatedly declared  Navalny  would be ineligible to run. Twelve members of the 13-member commission voted to bar  Navalny . One member abstained  citing a possible conflict of interest.
 Navalny   41  who polls show would struggle to beat incumbent Vladimir Putin in the March election  said he would appeal and called on his supporters to boycott the election and campaign against it being held.
“We knew this could happen  and so we have a straight-forward  clear plan ”  Navalny  said in a pre-recorded video released immediately after the decision.
 Navalny  said  he  would use  his  campaign headquarters across Russia to support the boycott and monitor turnout on voting day  March 18.
Polls show Putin  65  who has dominated Russia’s political landscape for the last 17 years  is on course to be comfortably re-elected  making  him  eligible to serve another six years until 2024  when  he  turns 72.
 Navalny  says Putin’s support is exaggerated and artificially maintained by a biased state media and an unfair system. He says he could defeat him in a fair election  an assertion Putin’s supporters have said is laughable.
‘DO  THE RIGHT THING’

Before the commission voted   Navalny   dressed in a dark suit  had demanded  he  be allowed to take part in the election delivering a speech that angered election officials.
In one heated exchange   he  said Russian voters’ faith in the system hung in the balance.
“If you do not allow me to run  you are taking a decision against millions of people who are demanding that  Navalny  take part ”  he  said  referring to  himself  in the first person.
“You are not robots  you are living  breathing human beings you are an independent body ... for once in your lives  do the right thing ”  he  said.
 His  supporters clapped  him   but officials were unmoved.
Ebzeev said there could not be “the slightest doubt” that  Navalny  was ineligible to run  a reference to Russia’s constitution that bars him running because of his suspended sentence relating to an embezzlement case.
 Navalny  has repeatedly denied any wrongdoing  and says the case is politically motivated.

ROUGH CUT ( NO REPORTER NARRATION ) U . S . Defense Secretary Jim Mattis on Tuesday played down an apparent split between the U . S . president and his top diplomat over outreach to North Korea   saying America ' s focus was still on finding a diplomatic solution to the dispute with Pyongyang . President Donald Trump   who has traded insults and threats with North Korean leader Kim Jong Un in recent weeks   said on  Sunday Secretary of State Rex Tillerson  was " wasting  his  time " trying to negotiate with North Korea over its nuclear weapons program .  Tillerson    during a trip to China on Saturday   said the United States had direct channels of communication with the North and was probing Pyongyang to see if it was interested in dialogue . He expressed hope for reducing tensions with North Korea   which is fast advancing toward its goal of developing a nuclear - tipped missile capable of hitting the U . S . mainland . " I do not see the divergence as strongly as some ... have interpreted it  " Mattis said . " President Trump ' s guidance to both Secretary Tillerson and me has been very clearly that we would ... pursue the diplomatic effort to include with the various initiatives with China  " Mattis told a Senate hearing . " I believe that Secretary Tillerson is accurately stating that we are probing for opportunities to talk with the North . All we ' re doing is probing . We ' re not talking with them   consistent with the president ' s dismay about not talking with them before the time is right ."

The Purple Line will begin carrying passengers in the Maryland suburbs later than expected because of a court fight over the project  but state officials believe it can still open in 2022   state Transportation Secretary Pete K. Rahn  said Thursday night.
The line had been scheduled to open to riders in March 2022.  Rahn  said the state and its contractor are still redoing the construction schedule  but  he  believes it can open âsometimeâ later that year.
âWe know there are going to be some delays â  Rahn  told the audience at a Silver Spring forum sponsored by the Purple Line Now advocacy group.
 He  said state officials should have a better sense of the timing â and any additional costs to the projectâs $2.4 billion construction costs â in a couple of months.  He  said  he  expects that project officials can make up some of the time lost during the one-year legal fight over the lineâs environmental impacts. A second lawsuit filed against the project is still pending in federal court  but judges have allowed construction to continue.
Early construction work has focused on cutting trees  particularly along the Georgetown Branch recreational trail between downtown Silver Spring and downtown Bethesda  and beginning to move utility lines.  He  said 75 percent of the design work is complete  and the state has acquired 88 percent of the right of way needed along the alignment.
The stateâs contractor  a team of companies called Purple Line Transit Partners  has about 375 people working on the project and will ramp up to about 1 500 people this year   he  said.
 Rahn  told the crowd the state has spent $200 million of the $325 million in federal aid that Congress has appropriated to the Purple Line. The state expects the rest of the total $900 million in federal grants to be doled out in annual appropriations of about $100 million to $125 million   he  said.
âWe are spending money quickly â  Rahn  said.
The state still expects the line to attract about 59 000 trips per day when it opens   he  said. That number is expected to grow to 74 000 daily trips by 2040.
âIf the service is as good as we think itâs going to be â  he  said  âIâm very confident in those numbers.â
