India 759-7d (190.4 ovs) vs England 477 | Scorecard

Karun cuts a short ball from Rashid through point for a four to bring up his 300, from 381 balls, having hit 32 fours and four sixes. And with that, India declare their first innings as Kohli calls his players back into the dressing room.

He becomes only the second Indian after Virender Sehwag to hit a triple hundred in Tests, who also hit 319 in Chennai, against South Africa in 2008.

This is only the third triple hundred in the history of Indian Test cricket after Sehwag's 319 and 309.

India declare their first innings on 759 for seven in 190.4 overs to finish with a massive first-innings lead of 282 runs.

This is India's highest ever score in Test cricket, beating the 726 for nine declared they made against Sri Lanka in Mumbai in 2009. This is only the fourth time that India have gone past the 700-run mark, in Test cricket.

He walks off to a standing ovation from the Chennai crowd, while all the England players walk up to him to congratulate him on his feat.

England have around five overs left in the day's play and the whole of the fifth day on a pitch, which has started to play some tricks.
