Royal Bank of Scotland CEO Ross McEwan has pledged to help address a lack of diversity in British boardrooms by combating a “too white and too male” culture.

His comments come after the Government-backed Parker Review, which found “disproportionately” low levels of diversity across UK boardrooms.

McEwan told BBC Radio Scotland: “We’ve set ourselves the target of having initially 30% of our top 700 executives as females by the end of 2020.

“We actually reached that target last year, so have changed the target to make it more difficult.

“Ethnicity, I think, is a big issue for this organisation.

“We need to be reflecting the types of people our customers are.

“Too white and too male is something that we’re now starting to concentrate on.

“I think it’s beyond the male and female and I think there are a lot of other areas that we should be thinking about as well.”
