Akash Deep's maiden Test fifty capped a frustrating morning for England, who waited nearly the entire session to strike on a pitch where the ball's still doing plenty. India added 114 runs to their overnight total, stretching their lead to 166 and tightening their hold on the fifth and final Test.

It was Jamie Overton who eventually broke through with a leading edge that carried to point, but not before Akash had delivered a standout performance. So assured was the nightwatch batter that Yashasvi Jaiswal, batting on 85 at Lunch on Day 3, played second fiddle through the session as Akash raised three successive milestones: his highest Test score, a maiden international fifty off 70 balls, and then his best-ever first-class score. He also became the first Indian nightwatch to score a fifty since Amit Mishra's 84 at the same venue against the same opponent back in 2011.

The batter got going with a heave against Jacob Bethell, the left-arm spinner who bowled the first over of the day in a stopgap move as the seamers changed ends, and that stroke seemed to set the tone, both for him and for India. He didn't shy away from taking on pace either, ausing the long handle against both Gus Atkinson and Josh Tongue with confidence. Stay tuned for more updates!
