A couple of queries about the tactics of proxy voting, apols if this should be obvious from the information already provided...
Firstly, are there any advantages in leaving it to the proxy to vote as they see fit rather than ticking the boxes? For example, is it possible that new or changed motions can be put forward on the day that the proxy can deal with better if left with an entirely free hand?
Secondly, what happens if the proxy is unable to attend on the day, for example through sickness? Is it sensible to try to find a greater number of people volunteering to be proxies, so as to spread the risk?
