The Swiss Post Office's banking arm said on Monday that it had closed an account set up by WikiLeaks founder Julian Assange after he gave false information.

"PostFinance has ended its business relationship with WikiLeaks founder Julian Paul Assange," the bank said in a statement.

"The Australian citizen provided false information regarding his place of residence during the account opening process."

Assange had given an undisclosed address in the Swiss city of Geneva as his residence, it added.

WikiLeaks had advertised the PostFinance account details online to "donate directly to the Julian Assange and other WikiLeaks Staff Defence Fund," giving an account name of "Assange Julian Paul, Geneve."
