Well, I wouldn't call it "even handed". The report is a little breathless, after all. Which is not surprising, given that The Sun is the most pro-Blair UK tabloid (the UK papers make no pretense of being neutral and objective, quite unlike the US mainstream media elite poseurs).
Nonetheless, the Sun will be a vastly more reliable source of information on Iraq than the NYT, LAT or ABCCBSNBCCNN.
There is a definite pro-Blair bent, but, as you indicated, it is far more accurate than the crapola we are getting in the USA. On a scale of 1 to 10, if "5" is the absolute truth and the lower numbers are liberal, this article is a "6" while the NY Times, et al, are hovering in the 1-2 range.
