It’s long been said he has a conflict of interest:
From the conservatve side of UK newspapers, seeing as you felt the Guardian was too left:
‘Tony Blair ’visited Libya to lobby for JP Morgan’ – Daily Telegraph, London- 18 Sep 2011
‘On the desert trail of Tony Blair’s millions’ By Peter Oborne, Daily Telegraph – 23 Sep 2011
‘Why Tony Blair must stand down as Middle East peace envoy’ Opinion piece by Peter Osborne, Daily Telegraph Political Editor, 14th June 2014 (the 2 earlier links I obtained from his op-piece)
The Guardian on the Oil for Food programme (I just grabbed the 1st 3, you ca google for more if you prefer, there were quite a few more):
‘Head of UN oil-for-food programme suspended over ’misconduct’‘ Guardian – 08 Feb 2005
’UN oil-for-food chief took Saddam bribes’ Guardian – 04th Feb 2005
‘Oil-for-food report condemns ’corrupt’ UN’ Guardian – 07th Sept 2005.
Church, Blair is a smarmy, lying, opportunistic, conflicted and morally corrupted individual. Left and right of aisle dislike him.
