Walden’s appointment follows the departure of Guto Harri who held the role during the Mayor’s first term and recently took up a job with News International.
As well as the BBC Walden has worked for ITN, GMTV and Granada and was senior political producer to Andrew Marr during his time as the BBC’s Political Editor.
Announcing the appointment Mayor Johnson said: “I’m delighted that Will Walden will be joining my team at City Hall.
“He will bring drive, originality and flair to the post of Director of Communications. It is ever more vital that politicians communicate clearly and honestly with voters about how we are spending their money and how we plan to improve the city.
“I believe Will has exactly the right skills to help us engage with Londoners. He has enormous experience of politics and a great track record at the BBC. I am thrilled to welcome him on board.”
Walden said: “After 12 year fantastic years at the BBC, I’m delighted to be joining Boris Johnson and his team at what is an incredible time for London and for Londoners. A Diamond Jubilee and an Olympic Games represent among the very best that London has to offer.
“But I know that the Mayor is determined it doesn’t end there. He has set out a compelling vision for London’s future and it is a privilege to be asked to help shape that vision.”
Earlier this week Labour Assembly Member John Biggs called on the Mayor to restore the regular City Hall press conferences held by Ken Livingstone and which Johnson scrapped on taking office.
Johnson replied that he held regular photo opportunities around London where the press were able to question him about his policies.
Walden will take up his new role in July.
