Richard Berry was once told by the Government to 'stop writing to the Australian Prime Minister as it is not possible for him to be your pen pal'.It took four more years of weekly letters without a reply from John Howard for Richard to realise they were right.In Dear Mark/Kim he sets out to see if Opposition Leaders make better pen pals. Collected here are forty of his best letters to Mark Latham and Kim Beazley plus the replies he's received from Canberra.
