Input: Consider Input: The Soros-backed Best for Britain group working to overthrow the government and block Brexit is “undemocratic”  according to  founder Gina Miller .
 Miller  became well-known as an opponent of Brexit after using the Supreme Court to force the Government to seek Parliament’s approval to activate Article 50 of the Lisbon Treaty and kick off the Brexit process  which could have seen MPs vote down the will of the people.
The group is working to build a network of powerful allies to undermine the Government before it can implement the Brexit vote  and  Miller  is insisting the public has the “right to know” who is backing it as it fights the referendum result.
In her statement   Miller  slammed the lack of “transparency about key players’ motivations  agendas and activities”  and urged “those keen to play their part in the Brexit debate to be open and honest about what they stand for  whom they represent and by whom they are funded”.

Input: Consider Input: 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.

Input: Consider Input: UNITED NATIONS (AP) — Secretary-General Antonio Guterres is again calling on the U.N. Security Council to refer Syria to the International Criminal Court  pointing to "serious violations" including blocking aid deliveries and medical care to millions.
 Guterres  said in a report to the council circulated Friday on the humanitarian situation in Syria in December that "accountability for serious violations is a requirement under international law and central to achieving sustainable peace."
During December   he  said  no aid was delivered to over 417 000 people in nine "besieged" locations  and only 60 000 of the nearly 2.5 million Syrians living in "hard-to-reach" areas received humanitarian help.  He  said 95 percent of the besieged population is besieged by Syrian government forces.
 Guterres  said "access for the United Nations and its partners to those people living in besieged and hard-to-reach locations remained a critical concern."
 He  said deliveries of food and other aid remained "extremely challenging" in many areas last month "as a result of active conflict  shifting conflict lines  administrative impediments and deliberate restrictions imposed on the movement of people and goods by the parties to the conflict."
