“[Lord Blair] took hold of the Met and forged a much better relationship with MI5 in the wake of the 7/7 bombings.
“Some of his big things were diversity and he reformed the way the Met recruited – people from ethnic communities.
“He was a big supporter of neighbourhood policing. Although that, over the years, dwindled due to a lack of funding. But it’s more or less the model police forces across Britain are reintroducing.”
Lord Blair quit his role in 2008 after saying he didn’t have the confidence of then-mayor Boris Johnson.
Viewed as a liberal figure, he was sometimes jokingly referred to as “PC Blair” by other officers.
He joined the police in the 1970s and served with other forces before joining the Met. His early work as a detective in London included investigating the fatal 1987 King’s Cross fire.
Senior positions for the Thames Valley and Surrey forces followed before he returned to the capital as deputy commissioner – and then the top job.
Lord Blair was a crossbench peer and was active in the House of Lords right up until his death.
