Deleted all the sources that were not the statement.
And checked California Transparency Act because:
This statement is made in compliance with the California Transparency in Supply Chains Act, and the UK Modern Slavery Act 2015.
Pg 1
"This statement is made in compliance with the California Transparency in Supply Chains Act, and the UK Modern Slavery Act 2015. It is also made in accordance with the expectations that any reasonable consumer would place on a global retailer such as Gap Inc"
This confirms that the UK companies and Gap Inc. boards have considered and approved the statement for fiscal year 2020. (p.1)
FY 2020 but exact date not disclosed. It refers to actions taken at the end of 2020 so likely to be correct.
