England lost three top-order wickets before the close as India surged towards victory in the second Test after their captain Shubman Gill's run-fest continued at Edgbaston.

Further shifts came with consecutive boundaries off spinners Washington Sundar (two fours through cover) and Ravindra Jadeja (a cut through point, then a launch back over the left-arm bowler's head), bringing Smith in with a shout of taking the record for England's fastest Test century.
