Who is he?
Tony Giddens is the UK's pre-eminent sociologist. He is also the leading New Labour guru, one of the moving spirits behind the now international debate revolving around the concept of the 'Third Way' (which could be defined as modernised centre-left politics). Giddens is 62.
How did he get here?
Giddens taught at Cambridge for many years, where he was a Fellow of King's College and a prolific author. He founded his own publishing company, Polity Press, in 1985. In 1997 he was appointed director of the London School of Economics.
What he's written
Sociology (1989); The Third Way and its Critics (2000); and, with Will Hutton, On The Edge (2000).
What they say about him
'He knows what he is talking about. Whether what he is talking about is more than light and mirrors you'll have to decide for yourself' - Kim Fletcher, former editor of the Independent on Sunday.
'Marx thought that the working class would bury capitalism, but as it has turned out, capitalism has buried the working class.'
If Blair's Third Way is going to have any life left in it after the next election, it may fall to Giddens to provide the inspiration.
