The sad news that Gordon Brown's baby son has cystic fibrosis made me think about Dominic McElroy.
Dom was my flatmate in about 1998 and a member of the Labour Students National Committee with me.
He tragically died from cystic fibrosis in 2001 when he was only 27 years old.
Although he knew that he was not likely to live a long life and had to constantly remember medication and diet and go for check-ups he never made a fuss about his condition (most people who met him in politics were unaware of it) and in fact dedicated himself to Labour Party activism - packing in more voluntary and professional work for the Party into his 27 years than many people do into decades.
