One of two bugs in your tea your Majesty?
The samovar was identified as a potential bugging device following a recent sweep by the security services at Balmoral.
The ornate red and yellow urn was presented to the Queen by a Russian aerobatics team about 20 years ago, at the tail end of the Soviet era.
Astonishing the lengths those guys went to gather information. I doubt much of substance other than the weather would be discussed in the Queens Drawing Room.
