Virat Kohli dropped a bombshell by quitting Test captaincy following the unexpected series defeat against South Africa.

Kohli was appointed Test captain back in 2014 when MS Dhoni stepped down in the middle of the series against Australia. "Everything has to come to a halt at some stage and for me as Test captain of India, it's now. There have been many ups and also some downs along the journey but there has never been lack of effort or lack of belief," Kohli wrote in a statement which he posted on Twitter, taking everyone by surprise.
