The Queen's art collection has reportedly joined the Russian boycott by withdrawing permission for three swords to go on display at an exhibition in Moscow.
The 17th century weapons, including one thought to have belonged to Charles I, were due to be loaned to Kremlin Museums for an exhibition on duelling that had been due to start this month.
However, according to the Guardian, the Royal Collection Trust decided to reverse the decision to allow them to go on show in the Russian capital in mid-February.
