Fae
 
I don't know you well - I've met you a few times - and I don't know the details of the dispute however:
 
* Arbcom is the highest court on en.wikipedia
* Arbcom only only ban a few people each year
* Arbcom have criticised your behaviour and banned you from Wikipedia 
 
In view of the above I believe that you should resign as chairman of WMUK.
 
If you believe Arbcom have acted in error then the appropriate course is to appeal that decision or to call for the restructuring of Arbcom..
 
I am very sorry that it has come to this and I hope this issue is resolved but, until it is resolved, I believe it is not appropriate for you to occupy such a prominent position in WMUK.
 
Yours.
