Tom Westley has been spared the axe as England named an unchanged 13-man squad for the third Test decider against West Indies at Lord's next week.

Westley's place has come under scrutiny following three single-figure scores in the Investec series as he has struggled to convince that he is the long-term solution to the problem No.3 position in the batting order.

But, in their final Test before this winter's Ashes, England have decided to keep faith with the Essex batsman and it seems he will be given another opportunity to press his claims for the trip to Australia.

Mark Stoneman and Dawid Malan, both of whom made important second-innings half-centuries in the five-wicket defeat to the Windies at Headingley, have also been retained as England opted against bolstering their batting line-up.

England will be looking to bounce back at the Home of Cricket following their surprise defeat this week, when the Windies chased down 322 thanks to Shai Hope's inspired 118 not out and a battling 95 from opener Kraigg Brathwaite.

Ottis Gibson, meanwhile, has decided to step down as England bowling coach to take over as the head coach of South Africa.

Gibson, who began his second stint with England in early 2015, will leave his post at the end of the Test series against West Indies.

"I would like to place on record my thanks to Ottis Gibson for his services to English cricket," said England and Wales Cricket Board director Andrew Strauss.

"Ottis has been an integral part of the England team in his two stints as bowling coach.

"His experience, tactical awareness and understanding of bowling in all conditions has benefited our approach and has helped our bowling unit develop greatly across all formats of the game.

"He is an ambitious man and when this opportunity presented itself it was difficult for him to turn down.

"On behalf of the ECB, I would like to wish him every success in the next chapter of his career."

In other news, Pakistan batsman Sharjeel Khan has been given a five-year suspension for his role in a spot-fixing case.

The 28-year-old, winner of 41 international caps across all formats, has been given the punishment by the Pakistan Cricket Board.

However, the PCB said in a statement that Khan would only serve half of the ban, with the other half suspended due to "mitigating circumstances and good conduct during the hearing".

The decision relates to "agreeing to fix" the Pakistan Super League match played between Islamabad United and Peshawar Zalmi in Dubai earlier this year.

A statement from PCB chairman Najam Sethi read: "The anti-corruption tribunal verdict against Sharjeel Khan is a vindication of our policy of zero tolerance against corrupt practices in the game of cricket.

"The PCB anti-corruption and vigilance department deserves great credit for identifying the culprits and nipping the spot-fixing scandal in the bud through their prompt action.

"The PCB fully backed the anti-corruption and vigilance department as soon as the plot to corrupt the opening game of the Pakistan Super League 2017 season was unearthed.

"The PCB's legal team worked tirelessly with the anti-corruption and vigilance department over the course of the last six months to bring Sharjeel Khan's case to its logical conclusion."

It added: "The PCB will continue to fight all corrupt elements that attempt to tarnish the game both at the domestic and international level."

Reports in Pakistan suggested Khan would exercise his right to appeal against the verdict.

Two players, Mohammad Irfan and Mohammad Nawaz, have already served suspensions, while others are awaiting decisions.
