Have a look at the PIRC website (I think there is one) and look for examples of voting on governance issues. The ABI might be a good place to look, too, as they often advise institutions on how to vote on contentioous issues like executive remuneration/compensation - pay to the rest of us.
You'd do well to remember that the small shareholder has almost no power, and even if ALL the small shareholders voted together, they'd easily be outvoted by the institutional shareholders.
Remember, too, that it is only quite recently that the institutional shareholders have put their heads above the parapet - for years they had a 'quiet word' behind the scenes rather than vote against publicly and we, the public or the small shareholders, never knew anything about it.
