Boris's olive branch in Olympic row
I understand that a breakfast meeting took place this morning when Johnson agreed to drop his campaign for the shooting events to be moved from Woolwich to the east London borough of Barking.
In return, Jowell agreed to back the Mayor's hopes of moving the badminton and rhythmic gymnastics to Wembley.
The disagreement had lead to what officials described as an "acrimonious" Olympic board meeting two weeks ago when Johnson vetoed 2012's plans.
Last week the International Olympic Committee said it was a matter of "urgency" that the row was solved before the end of the year.
Johnson and Jowell will now put their backing behind 2012's hopes of persuading badminton and rythymic gymnastics to move to the Wembley Arena.
This allows 2012 to save at least £20 million because they will not need to build a temporary venue for the sports near the 02, the original plan put forward to the IOC during the bid.
A meeting was due to take place later today to discuss the move between 2012 and international gymnastics officials, who are in London for the world championships at the 02 Arena.
The decision is a boost to Woolwich whose Labour MP Nick Raynsford staged a protest at City Hall last week about the Mayor's plans.
Barking will not lose out in the process, however. Jowell plans to give it the status of an Olympic borough and spend £500,000 on creating training facilities in the east London borough for visiting teams.
The venues row was one of the biggest controversies of the Games so far.
2012 have been trying to find agreement with the IOC and badminton and rhythmic gymnastics for more than a year now.
But sports officials have been reluctant to make the move because it will mean more travelling for competitors from the Olympic village in Stratford in east London.
This will be a key issue at today's meeting.
Johnson is adamant that cost-cutting must take place in the Olympic budget and says a temporary venue would be a waste of taxpayers cash.
