A complaint that a sustainable investment advertisement by Barclays Investment Bank was misleading - because it omitted significant information about the bank’s contribution to carbon dioxide and greenhouse gas emissions - has been rejected by the advertising watchdog.

Barclays Bank has been fined £40m for failing to disclose a fund raising deal with Qatari entities in 2008 at the height of the financial crisis in that year.

The former chief executive of Barclays Wealth during the 2008 financial crisis has been banned from performing senior manager functions.
