Oscar: Los Angeles's most famous resident may be moving

They are calling on the Local Agency Formation Commission, which analyses secession attempts, to change the proposed city's boundaries so that the sign will remain in Los Angeles.

The Los Angeles mayor, Jim Hahn, is fighting the plan for the San Fernando Valley to break away from the city.

It is not yet clear what the proposed new city's name would be, but a vote on the proposed breakaway could happen as soon as November of this year.

A spokeswoman for councilman Tom La Bonge, who represents the area where the sign is located, said Mr La Bonge "will do anything in his power to keep it in Los Angeles".

Mr La Bonge had argued that lay on land bequeathed to Los Angeles for the city's exclusive use by one Colonel Griffith J Griffith.

However, supporters of the plan for a new city studied paperwork and found that the sign did not actually sit on Griffith's land.
