TOKYO (Reuters) - The British pound and the euro fell to their lowest level since 2013 against the yen on worries a UK referendum later this month could pull Britain out of the European Union, possibly disrupting European political and economic affairs.

The pound fell to as low as 151.50 yen <GBPJPY=R>, its lowest level since August 2013 while the euro fell to 119.87 yen <EURJPY=E>, a level last seen in April 2013, as the yen has become something of a safe haven.
