Panama Papers: Labour urges tax havens probe

Labour leader Jeremy Corbyn has called for an independent investigation into the tax affairs of all Britons linked to millions of leaked documents from a Panama-based law firm, including David Cameron's family.

The huge data leak from Mossack Fonseca shows it registered thousands of secret companies for wealthy clients.

The government said Mr Cameron had spearheaded international action to improve tax transparency and personally owned no shares in any company.
