Mayor Khan launches #LondonIsOpen campaign

London mayor Sadiq Khan has launched a major campaign to show that London is united and open for business and to the world following the EU referendum. #LondonIsOpen will show the world that London remains entrepreneurial, international, and full of creativity and possibility, while reassuring the more than one million foreign nationals who live in London that they will always be welcome, and that any form of discrimination will not be tolerated.
