JACKSON, Miss. (AP) - Legislative leaders say plans for new district lines for the House and Senate have been delivered to the Department of Justice.

House Elections Committee Chairman Bill Denny, a Republican from Jackson, tells the Northeast Mississippi Daily Journal (http://bit.ly/PpRkyi ) that the legislative plan was delivered this week.

The 122 House districts and 52 Senate districts have to be updated after each Census to account for population changes. Between 2000 and 2010, there was significant growth in DeSoto County, just south of Memphis, and it's getting new legislative districts.

Because of Mississippi's history of racial discrimination, the redistricting plans need approval of the Justice Department, which checks to ensure the plans don't dilute minority voting strength.

One Democratic lawmaker says objections to the plan will be filed with the Justice Department.
