Speaking on the Andrew Marr show, Jeremy Corbyn urged the UK to make Crown Dependencies adopt more transparent tax policies.
Asked whether the UK should impose direct rule on British Territories, he replied that: “There are various measures one can take.”
The Opposition leader said the Pamama Papers leak a week ago showed there was “one rule for the rich, and one rule for the rest”.
Following the revelation that his late father held assets in an offshore trust, Prime Minister David Cameron published details of his own tax records for the past six years.
Despite the records showing Cameron did not benefit from income from offshore trusts, Corbyn said there were still questions to be answered, and urged others in politics to reveal their tax records too.
Jeremy Corbyn’s remarks do not go as far as his calls last week to impose direct UK rule on overseas territories after the leak showed there were more than 100,000 secret firms registered in the British Virgin Islands.
Over 11 million files from Mossack Fonseca, a Panamanian law firm specialising in setting up offshore companies, have been leaked.
Names in the files include over 70 heads of state.
Revelations of the tax affairs of individuals around the world have led to fears of invasion of privacy and the resignation of Icelandic Prime Minister, Sigmundur David Gunnlaugsson, over accusations of tax evasion.
Mossack Fonseca’s directors have denied any wrong-doing and have attributed the leaks to their client data base being hacked.
Jersey, along with other overseas territories such as Gibraltar and Bermuda, has already complied with UK demands for the automatic exchange of tax information, a common reporting standard for multinational companies, and the registry of beneficial owners of companies.
