City officials said that they believed that the authority lacked the resources and expertise to consider major decisions properly.
The move comes after the ODPM mooted proposals late last year to ramp up London mayor and GLA-chief Ken Livingstone's influence on strategic planning decisions.
These new powers would allow Livingstone to give the green light to large developments, whether local councils backed them or not.
In a report to be considered by Corporation councillors early next week, the local authority's planning department has damned the GLA's expertise and knowledge of planning issues.
The briefing also raises the concern that if the GLA were to take control of all strategic planning decisions, it would create recruitment problems for local authorities.
