"This is the age of Edward Snowden, not Edward Windsor."  That's part of a stark warning to the monarchy from PR expert and strategy consultant Robert Phillips, who will deliver the annual John Campbell Lecture on Monday.

Phillips is to argue that with the demise of PR the monarchy is in real trouble.

Phillips, author of 'Trust Me, PR is Dead' and former CEO, EMEA, of Edelman will deliver the annual John Campbell Lecture on Monday, November 30 at the Amnesty International Human Rights Centre in Shoreditch.

Phillips argues that PR is dead and this spells trouble for any institution - monarchy included - that tries to spin, deceive or manage the message. In an age of activism and networks, crumbling hierarchies and tired elites are unlikely to survive.

In the lecture Phillips will say:

"Spinning your way to success died with the last century - Palace Press Office, take note."

"The mega trend of individual empowerment is eroding trust and belief in all institutions. There is no logical reason why monarchy should not suffer a similar fate."

"Hierarchical institutions can only fail in a networked society. Monarchy is the ultimate hierarchy. The transition from Elizabeth to Charles may well be the equivalent of a royal Corbyn moment."

"The message for leadership in the new normal is clear: do the right thing or "we will get you". Resistance is futile."

"The trustworthy organisation of the future is open, empathetic and shared .... not behaviours the monarchy shows in abundance."

The John Campbell Lecture aims to give a platform to leading thinkers and campaigners, to raise issues around reform and democracy.  The annual event is hosted by Republic, the campaign for a democratic alternative to the monarchy.

Graham Smith, Republic's CEO, said today:

"We're delighted that Robert will be delivering this year's lecture.  His book, 'Trust Me, PR Is Dead' has caused a real stir and I have no doubt what he has to say on Monday will be just as provocative."

"The monarchy relies on the careful management of its image.  It demands secrecy so that the public only sees what it wants to see.  That's a dangerous place to be."
