No, he hasn’t been given the sack but he does need to know where to stand.
Last Tuesday, our trusty and well beloved DC (it must be true, they put it on the certificate) was presented with his certificate for being appointed Grand Tyler. Interestingly, the use of the word ”and” on the certificate implies that he not only has the job for the next 12 months but that he is also required to do it “until a successor is appointed in his stead”. This means that, if no one else wants the job, he is required to do it ad infinitum.
