WASHINGTON, November 14--The House Republican steering committee today agreed upon a 20 percent individual income tax cut, an eight year limit to the President's tenure, and "constructive" labor legislation.

That preliminary legislative program was agreed to by a score of party leaders, including members of the policy-shaping steering committee and other congressmen who sat in at the first meeting since Republicans won control of Congress in last week's elections.

The group, presided over by Representative martin of Massachusetts, who will become Speaker of the House when the new Congress convenes on January 2, also called for:

"Substantial savings on a practical basis."

Elimination of governmental controls and termination of Presidential war powers as rapidly as practicable."

Investigation of the housing program and removal of "restraints now holding up proper progress."

"The quickest possible comprehensive recommendation" for relief from shortages in sugar, soap, fats, oils and foods.

Close adherence to the Congressional reorganization act "with appreciation of the fact the experience or later developments might demand clarification and improvement."
