Boris Johnson today admitted that the total cost of the 'transition team' of consultants, Tory HQ fixers and PR spinners is likely to be well in excess of half a million pounds.
The admission contained within his written answers to Assembly Members comes one week after he suggested that the cost would be less than half of that amount.
Speaking at Mayor's Question Time, Boris told the assembly that the transition team would only cost £213,000.
However, it is now clear that this only refers to the cost of the fifteen people employed within the Mayor's office.
Because what Boris admitted today is that there are another seven hitherto unacknowledged 'transition consultants' working elsewhere within the GLA.
The total cost of all 22 consultants is now thought to be anything up to a maximum of £565,000.
When I first highlighted the existence of the transition team, the Mayor's office refused to admit how much they would cost.
However, what is now clear is that even when they finally did release the cost, they excluded seven of the highest paid consultants from the run-down.
In fact even the existence of these consultants, including the 'Director of Transition' himself, were withheld from the public. They have only now been released three months after they began work at City Hall.
Because when Boris Johnson came into power he promised to make all GLA spending available 'from day one.'
But with misleading and contradictory figures continuing to be released by his administration, he is now a very long way from meeting that aim.
