On 27 April 2010, Russia and Ukraine ratified the Russian Ukrainian Naval Base for Gas treaty, which extended the Russian Navy's lease of the Crimean facilities for 25 years after 2017 (through 2042) with the option to prolong the lease in five-year extensions. The ratification process in the Ukrainian parliament encountered stiff opposition and even resulted in a brawl in the parliament chamber. Eventually, the treaty was ratified by a 52% majority vote—236 of 450. The Russian Duma ratified the treaty by a 98% majority.
