This move is firstly a response to the unprecedented chemical attack in Salisbury, thus along with other allies expressing unity and solidarity with the UK, and secondly to the false allegations by the Russian Federation that the Czech Republic was a potential source for the Novichok agent used in the attack.

Prime Minister Andrej Babiš explained his government's decision as follows: "We are a solid part of the Western Bloc, and the British Prime Minister May has personally asked me to take this step. And when our ally asks for help, we should meet this ask. Russians crossed all red lines when they declared that the poison used in the attack in the UK could come from the Czech Republic."
