Issued by the United Kingdom in 1980, this 12-pence commemorative stamp marks the 62nd Inter-Parliamentary Conference held in London. The design presents a detailed aerial illustration of the Palace of Westminster, including Big Ben and Westminster Bridge, rendered in blue and gray architectural tones. The golden silhouette of Queen Elizabeth II appears in the upper right corner, signifying British sovereignty. The issue celebrates international parliamentary dialogue and the democratic tradition symbolized by the historic Houses of Parliament.
