June 23 (Reuters) -

Omnicom's ( OMC ) $13.5 billion acquisition of rival

Interpublic can move forward on the condition that the

new company does not enter agreements with others to steer ad

dollars towards or away from publishers based on political

content, the U.S. Federal Trade Commission said on Monday.

The deal would still allow individual advertisers to specify

where their ads are shown, according to the agency.

Spokespeople for the companies did not immediately respond

to requests for comment.

Omnicom ( OMC ) struck a $13.25 billion all-stock deal in

December to buy rival Interpublic Group, creating the

world's largest advertising agency.
