Ex-Premier Robert Fico chairs the biggest party in Slovakia. Last week, he called for a special parliamentary session on the country's gold. He said the country's gold reserves are not safe in England because of Brexit and the possibility of a global economic crisis.

Fico said you can hardly trust even your closest allies after the Munich Agreement, referring to the 1938 pact that allowed Hitler to annex part of Czechoslovakia.

 I guarantee that if something happens, we won't see a single gram of this gold. Let's do it as quickly as possible."

Slovakia could follow the lead of Poland. Earlier this month, the National Bank of Poland announced that it had completed the repatriation of 100 tons of gold from London. NBP Governor Adam Glapi?ski said the gold "symbolizes the strength of the country."
