LONDON — London Mayor Sadiq Khan is calling on creatives to support the message that London remains open for business, despite the recent EU referendum result.

The Mayor's office, supported by agencies Freuds and London & Partners, has launched an open-source design brief to support the #LondonIsOpen campaign. Creatives have been invited to submit a visual interpretation of #LondonIsOpen, as the capital aims to spread the message that London is open for business, music, food, drink, sport, art and more.

Designs will be shared across social platforms and different media from billboards to theatres, at sporting and cultural events until the end of the year. They will also be showcased at City Hall during Open House in September.

"London is the best city in the world. It is entrepreneurial, international and full of creativity and possibility," said Khan. "The key ingredient of our success is the flow of ideas and talent from all over the world. After the referendum on the UK’s membership of the European Union, it’s now more important than ever to show that our city is united. As always, our capital will be open for business and open to the world."

"Now’s the time to make that message clear to everyone – that our city is comfortable in its diversity, proud of its history and optimistic about its future," he added. "London is open."

Ideas and designs can be sent to [email protected] with the title 'London is open submission' by 22 July.
