RBS has been fined for incorrectly reporting trading activity
Royal Bank of Scotland has been fined £5.6m for failing to properly report almost 50 million trades.
The fine relates to the period between November 2007 and February 2013 when regulators found mistakes in more than a third of the bank's transactions.
The Financial Conduct Authority said that problems at RBS were made worse by the takeover of ABN Amro Bank in 2007.
Mistakes included, failing to properly identify the parties in a trade and using the wrong date and prices.
