Steve Richards (pictured) will also deliver thought-leadership and media training.
He has written political columns for The Sunday Times, The Guardian, Financial Times and The Independent, and is a regular commentator on Sky and BBC.
“Steve is a hugely respected political figure and we’re delighted to welcome him,” said WA Communications managing director Dominic Church.
“He will bring unparalleled insight to our advisory board, both from a political and media standpoint. This unique blend of expertise is a perfect fit for WA.”
Richards said he had been “really impressed with WA’s strong growth and the expertise and commitment of its staff.
“At a time when politics is extraordinarily turbulent, I’m hugely looking forward to lending my experience and expertise to this dynamic and rapidly growing team.”
