Italy's public and private sector institutions owe nearly $50bn to British banks, figures reveal.
The statistics detail Italy's debt to the UK banking sector as the country remains in a political deadlock with no party securing an overall majority in the country's election.
Britain's banks' external exposure stood at $2.7 trillion in June last year, according to the Bank for International Settlements.
Italy's current debt to the UK is less than the $66bn the country owed at the end of 2010.
