Pakistan achieved the No.1 Test ranking for the first time since the current rankings system was introduced in 2003 after it played a two-all draw against England.
Pakistan's cause was also helped by Sri Lanka, which defeated Australia by 3-0, while a wet ground in Port of Spain denied India the opportunity to defend the top spot as they won their four-Test series against the West Indies by 2-0.
Pakistan are currently sitting on 111 points, one ahead of India, while Australia and England are on 108 points each. The top seven Test sides are separated by just 16 points.
