If any one man can be said to have Tim Parker's blood on his hands this morning, it is Boris Johnson's other Deputy, Sir Simon Milton.
When Milton met the London Assembly last month, he was asked why he had taken so long to accept a full time position. Milton replied:
I am probably to blame for that. The Mayor wanted me to come in full time from the beginning but I found that hard to agree to at first. But now I have decided that my place is here.
So what changed? Certainly nothing at the LGA who were pretty peeved to see him go. Nor at City Hall where lawyers continued to insist that his position as informal advisor was (just about) legal.
What did change it seems, was the job offer on the table.
Because when Milton's name first came up in May it was as an executive Director of Planning.
However, when it was pointed out that his roles at Westminster Council and the Local Government Association precluded him from the job, he was demoted to an informal advisor.
With his powers suitably stripped, Tim Parker was then brought in, largely to fill the void.
At his confirmation hearings with the Assembly, Parker spoke passionately (a little too passionately perhaps) about his desire to bring in affordable housing.
But when Milton of Shirley Porter fame, started to informally stretch his own informal powers from his informal office in City Hall, there was inevitably going to be a clash.
And when Milton decided that his 'place is here' he was dutifully handed many of the planning and policy powers which Parker had already been lined up for.
Arise Sir Milton
That Milton was on a power grab became even clearer last week when it was revealed that Boris would not be employing a Housing Advisor, despite his earlier promises.
This role like many of Parker's will now be exercised by Milton.
In a memo sent to all City Hall staff yesterday Boris Johnson confirmed:
"As you may by now have observed, Tim Parker has relinquished his role as First Deputy Mayor and Chief Executive of the GLA.
"I am hugely grateful to him for his help and support over the last couple of months, and he will continue to be giving me advice as a member of the board of TfL.The key factor in our decision – and yes, it was a joint decision – is that it has become quite obvious to both of us that the Mayor must chair TfL. This body is not just a major London employer. Decisions taken by TfL have an impact on the lives of millions of Londoners, and there must be direct political accountability.
"We will also be taking forward Tim's work on restructuring the GLA. He has come up with some excellent ideas, and these will now be developed by Simon Milton, who will be assuming greater responsibilities within my office, together with the interim Head of Paid Service, Jeff Jacobs. This plan will now be put into effect next month."
So as Parker packs up his suitcase, no longer able to 'make the difference' he wanted to, spare a thought for the new lord and master of City Hall. Farewell one and all to Prince Parker and arise my lords to Sir Milton.
