Hussain shocked English cricket when he resigned as Test captain on Monday, at the end of the drawn first Test with South Africa.

He is playing in the second Test, which began at Lord's on Thursday morning, but as a specialist batsman only.

His brother Mel Hussain told the BBC Sport website: "I would say with some degree of certainty that Nasser will not tour this winter.

"He wants his life back, to have Christmas at home, to go to a restaurant without having to field phone calls."

Nasser's second son, Joel, was born last November, in the middle of a tough Ashes tour that saw the England skipper appear mentally exhausted on the field of play.

Under new skipper Michael Vaughan, England face three Test tours during the English off-season, travelling to Bangladesh, Sri Lanka and the West Indies.

"The thought of going to Bangladesh for another series as a regular England player might not be as exciting as spending some time with his wife and kids," said Mel.

"He has given everything in the last 15 years and there's not a lot left.

"England are a stronger, more confident, better prepared side than when he took them on and the only thing they've not done is beat Australia."

And the older Hussain brother, who played county 2nd XI cricket himself, suggested Nasser would probably quit all cricket at the same time, ending his Essex career too.

"There is no suggestion he has set himself a time limit; it is purely a mental thing," he said.

"If he walked after this Test match I wouldn't be surprised - if he got two low scores.

"He will have some regrets but he has to look forward."

Mel has not talked to his brother since Monday's resignation, but he Believes Nasser will not feel any more relaxed now he has relinquished the captaincy.

"He has never been very good waiting to bat," he explained.

"Getting runs in the middle brings the same pressure as captaincy."

A career as a television summariser beckons for Nasser, who made his debut behind the microphone during last month's Twenty20 Cup.
