"Huge multi-nationals including Goldman Sachs, JP Morgan and UBS are yet to sign up to the Charter, and if they don’t intend to do so, the Treasury Committee wants them to explain why."
The Charter is a commitment by HM Treasury and signatory firms to work together to build a more gender balanced and fair financial services industry.
In the letter, Morgan asks if the firms will be signing the Charter, and if not, their reasons for not doing so.
She said: “The progress of the Women in Finance Charter is to be welcomed. The aim, however, must be to see all firms in the financial sector sign up to the Charter and make a concerted effort to improve their gender diversity, particularly in senior roles.
“As the Charter states, a balanced workforce is good for customers, profitability and workplace culture.
“Huge multi-nationals including Goldman Sachs, JP Morgan and UBS are yet to sign up to the Charter, and if they don’t intend to do so, the Treasury Committee wants them to explain why.”
