England have extended their lead to 173, having reached 325-8 at lunch on day three of the fourth Test against India at Old Trafford.

Resuming on 237-6, Joe Root and Jos Buttler continued their partnership, with both batsmen securing their half-centuries in the opening hour of play.

Root looked to be progressing towards a century, but edged a Pankaj Singh delivery to MS Dhoni, leaving him 23 runs short of the ton and giving the bowler his maiden Test wicket.

Singh continued to look dangerous, and managed to claim a second just before the break when Buttler hooked the ball to Cheteshwar Pujara.
