Joe Root should step down as England Test captain following his side's series loss to the West Indies, former skipper Michael Vaughan told the BBC.
Root's position is under the spotlight after a 1-0 series defeat which came on the back of a woeful 4-0 Ashes thrashing by Australia.
That extended England's poor run to four successive Test series defeats.
The 31-year-old Yorkshire star batter has skippered England in a record 64 Tests, winning 27 games -- more than any other captain -- but lost 26, which is also more than any other captain.
Vaughan, who captained England 51 times from 2003-08, has known Root for many years but says it is better to have Root in the side without the burden of the captaincy.
"He's taken it as far as he possibly can," Vaughan told the BBC.
"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."
Vaughan said he would prefer it if Root, who has expressed his desire to remain captain, resigned rather than was fired by the future permanent director of cricket and the head coach.
Former captain Andrew Strauss and Paul Collingwood are filling the roles of director of cricket and coach respectively following the departures of Ashley Giles and Chris Silverwood prior to the West Indies series.
"I wouldn't want the new director of cricket or head coach to sack him -- he's deserved the right to go on his own ground," said Vaughan.
"During his reign I don't think he has been helped at all.
"His first Ashes series there was the Ben Stokes incident (a late night fracas outside a Bristol bar), then we had the white-ball reset, then he's had Covid and it's been very difficult.
"But, I always think captains should pride themselves on maximising every ounce of potential in the changing room.
"I just look at the team and ask 'Why did they perform so under their potential?' That would be a real concern for me."
Vaughan says Root has lacked a clinical touch when it has come to matches that are delicately poised.
"Tactically he has been poor," said Vaughan.
