His faults and mistakes have been well documented and I could go on for pages and pages about those but I'd at least like to give him some recognition for the good things he did achieve.
He was instrumental in bringing peace to Northern Ireland after years of failure/apathy by other british PMs.
He introduced the European Convention on Human Rights into domestic legislation ensuring real protection for people's rights.
The tax credits system, (despite it's well documented flaws) has increased the income of thousands of families and has made a massive impact on the government's pledge to eradicate child poverty by 2020. And according to a recent UNICEF report, children in the UK now rank in the highest categories across Europe for "educational wellbeing".
Under Blair, the UK was one of only three states in the EU to open it's labour markets to the new accession states that joined the EU in MAy 2004.The influx of eastern european workers has massively boosted the UK economy.
He also modernised government, including importantly the House of Lords through his attack on the hereditary peers. (the fact that it also redressed the heavy Tory bias in the Lords was a fortunate coincidence
)
See, he wasn't all bad!!
