Patriarch Kirill of Moscow
Leonid Slutsky has close relations with the leadership of the Russian Orthodox Church. On 11 June 2011, the day of Orthodox holiday of Pentecost, Slutsky landed on the territory of Trinity Lavra of St. Sergius on a helicopter, without having warned anyone in advance. It "caused a great deal of surprise which turned into indignation among parishioners and workers of the church". According to the deputy, he hurried to meet with Patriarch Kirill of Moscow, but because of traffic jams on the Yaroslavl highway he had to use the services of a helicopter company.
