Take a look at the following screen captures from the English Democrats' website:
Note the words 'the Deputy Lord Lieutenant of Essex'. Not named and in any event it is likely there is more than one Deputy.
I queried the appropriateness of a DLL speaking at a political meeting and moreover one being held in Leicester in an e-mail to Essex County Council. The link I provided to the ED website now comes up as a 404 error. However I have the screen shots.
There is no reason why a DLL cannot hold political views and attend political meetings but surely this should be in a personal capacity. To publicise the DLL role is politicising a Crown appointment and should not be countenanced. Indirectly it has brought the sovereign into party politics.
