All white-boards at FTSE 100 firms should no longer exist by the year 2021. That's the recommendation in a new government-commissioned report out next week to bolster ethnic diversity in British companies.

It also will urge that the next 250 largest public firms should aim to appoint one non-white board member by 2024, according to a report by Sky News.

It has concluded FTSE-100 boardrooms are under-representing their workforces, customer bases and supply chains.

Speaking at a press conference, the chairman of the report, Sir John Parker, said: "I continue to support the importance of ethnic and cultural diversity, especially in British companies trading globally.

"Those of us privileged to lead company boards should ensure that ethnic diversity becomes a natural component in building strong and competent boards.

"I am a firm believer that greater diversity on boards leads to stronger, more balanced business decisions."

Sir John Parker is a British businessman, who is currently Chairman of Anglo American PLC and Ombu Group, Deputy Chairman of DP World, and a Director of EADS and Carnival Corporation & plc.

As the former chairman of the Bank of England's court, he was at the heart of the historic £500bn bailout rescue package for the Royal Bank of Scotland and Lloyds Banking Group in 2008.

Speaking to The Independent in 2010, he said: "I'm to the right of Genghis Khan, but even I would have nationalised the troubled banks."
