Jowell proposed that a temporary arena be constructed in Barking that would have hosted the two sports while Johnson wanted the shooting moved from the Royal Artillery Barracks at Woolwich and moved to the same site.

They will formally declare their support for the Wembley option at the next meeting of the London Olympic Board on Thursday.

London 2012 are already behind the plan and it is likely that the British Olympic Association (BOA), the fourth stakeholders on the Board, will also approve it.

Denis Oswald, the chairman of the International Olympic Committee's (IOC) London 2012 Coordination Commission, last week expressed concern that doubts remained over the venues for badminton and rhythmic gymnastics with less than three years to go until the opening of the Games.

Under the original plan by London 2012, boxing would have moved out of the ExCel Arena to Wembley to accommodate badminton and rhythmic gymnastics, which were supposed to be held in a new temporary built venue.

But officials have scrapped building that in an attempt to save £40 million.

Boxing refused to move because the venue is at least a 35 minute drive from the Olympic Village in Stratford and were supported by the BOA.

Badminton has also promised to strongly oppose any move but, as they are due to hold their World Championships at Wembley in 2011, they may not be in such a strong position to resist.

Brian Stocks, the chief executive of British Gymnastics, has already told insidethegames that he is happy for rhythmic gymnastics to be staged at Wembley Arena.

Officials from the world gymnastics federation (FIG) are in London this week for the World Artistic Championships at the O2 and will discuss the Wembley Arena proposal with 2012 officials.

Representatives of the International Badminton Federation (IBF) are due in London in the next seven days for similar talks.

A spokesperson for Johnson said: "The Mayor held a constructive meeting with the Olympics Minister this morning where they agreed a shared proposal to take to the Olympic Board meeting this Thursday.

"The agreement is now a matter for the Board and the Mayor invites them to recognise this proposal, which has the full backing of the two people that are elected to represent the interests of London voters, taxpayers and the wider electorate."
