Which was lord grenvilles plan to enforce new taxes?

Lord Grenville's plan to enforce new taxes included the Stamp Act of 1765, which imposed a tax on all colonial paper materials, and the Townshend Acts of 1767, which imposed duties on imported goods such as glass, lead, paint, and tea in the American colonies. These taxes were intended to help pay Britain's debt from the French and Indian War and to assert British authority over the colonies.
