there have been none who didn't make massive mistakes ,Blair did a lot of good things but his Iraq war was a huge problem for the folk I know who voted Labour and Brown was a great disappointment but might hav eredeemed himself IF he'd got the chance .I think I'd have to go much further back to find someone who believed in the things I do ,so I'm going for Robert Bontine Cunningham Graham ,co founder of the Labour party ,Independence supporter and first leader of the party that is now the Scottish National Party .A true socialist and a man who had an amazing life .For those who haven't heard of him google him,also known as Don Roberto
