Dutch Foreign Minister Halbe Zijlstra tendered his resignation on Tuesday after admitting to lying about attending a 2006 meeting with Russian President Vladimir Putin. "I see no other option today than to hand in my resignation to his majesty the King," a tearful Zijlstra told MPs in a hastily-called session of parliament. "This is by far the biggest mistake I have made in my career," he admitted to Dutch politicians in the lower house of parliament, watched by Prime Minister Mark Rutte. Stepping down, Zijlstra told MPs Tuesday that the credibility of the countrys foreign minister must be "beyond doubt, both inside and outside of the country." Zijlstra had only been in post for four months, and the dramatic events came just hours before he was due to leave on an official trip to Moscow to meet with Russian Foreign Minister Sergei Lavrov. He had been due to meet Wednesday with Lavrov to discuss among other things the 2014 downing of the Malaysian Airlines flight MH17 by a missile fired from territory held by pro-Russian rebels over Ukraine. The tragedy in which all 298 people on board died, most of them Dutch, has soured ties, and led to accusations that Moscow is not presenting all the evidence it has to a Dutch-led criminal inquiry. Zijlstra’s resignation came after his claims to have attended a meeting 12 years ago with Putin in his dacha which included Jeroen van der Veer, Shells former chief executive were revealed on Monday to be false. "I have spoken about an incident of great importance, saying I was there in person, while that was not the case," Zijlstra told MPS on Tuesday. "I wanted to tell this story convincingly without revealing my source was obviously the wrong choice. I should not have done it. I am sorry." A former Shell contractor, Zijlstra had told members of his Liberal VVD party at a congress in May 2016 that he was there "in the background as an assistant". During the meeting Putin allegedly spoke about his definition of a "Greater Russia". "I clearly heard Vladimir Putins answer about what his understanding was of Greater Russia," Zijlstra told the audience. Putin "wants to go back to a Greater Russia and his answer was that it included Russia, Belarus, Ukraine and the Baltic States," he said at the time. Zijlstras appointment in October as foreign minister within Ruttes fragile four-party coalition government had raised eyebrows because of his perceived lack of diplomatic credentials. But the Volkskrant said "his spin doctors" had used the story of the Putin meeting "to ward off criticism about his lack of foreign experience. Lawmakers also grilled Rutte, who had previously defended Zijlstra despite having known since late January that he had made up the story about Putin. The handling of the Zijlstra’s case is the first serious test for Rutte’s coalition since it took office in October. The Russian Embassy said in a statement that Zijlstra’s allegations “do not hold up against any criticism and are only intended to spread false perceptions of Russia’s intentions.” “Russia is being blamed for disseminating disinformation,” Moscow’s embassy in The Hague said in a statement. “Dutch officials are constantly making such unfounded statements... Isn’t this an example of fake news directed against our country?”
