Michael Vaughan believes Joe Root should step down as England captain after another Test series defeat.

England's dismal 10-wicket defeat to West Indies in the third Test in Grenada meant a 1-0 series reverse, coming off the back of a 4-0 Ashes thrashing at the turn of the year.

Those are two of five consecutive Test series defeats for England, who had won four in a row before then. They have not endured a worse such run since six without a win between 1987 and 1990.

England are also winless in nine Test matches, their worst sequence since a barren stretch of 10 between 2013 and 2014.

Alastair Cook survived that spell as skipper, but Root – the only man to captain England in more Tests (64 for Root, 59 for Cook) – is now under intense pressure.

And Vaughan, fourth on the list of matches as England captain (51), suggests the time has come for one of the world's best batsmen to focus solely on his own game.

"He's taken it as far as he possibly can," Vaughan told BBC Radio 5 Live.

"If he rings me in the next week and asks for some advice, I'll be dead honest: I'd tell him to step down.

"Will England be any worse off not having him as a captain? I don't think they would, because they are going to get his runs and a senior player.

"They'll get a great role model – I don't think there is a better role model in English cricket."

Root has averaged 46.4 with the bat as captain, down from 52.8 up to that point, with all 53 prior matches coming under Cook.

Only in 2013 (34.5) has his batting average been lower across a calendar year than his 35.8 so far in 2022.
