Stuart was brave enough to say I'm comfortable in doing what I'm doing and I think he has to stick with that Chris Broad

Broad said England bowling coach Kevin Shine had suggested that Stuart make some adjustments to his action.

But he told BBC Leicester: "I don't believe you should have a whole host of clones playing in an England side so that they don't get injured."

Shine will be in charge of England's bowlers for the Ashes series after replacing Troy Cooley in March.

And although Broad Jr is not in the squad, he could be called up from the Academy to provide cover in the event of any injuries.

His father, a member of the 1986-87 Ashes-winning team and now an ICC match referee, said coaches were suggesting changes to try to protect players from injury, but it was wrong to tinker with a natural action.

"I can understand where Kevin Shine is coming from in that biomechanics are saying as far as injuries go you have to open up a little bit more save your back," he said.

"But Stuart's is a very natural action, it's a very easy action and it's a wicket-taking action.

"Injury is part and parcel of any game. A coach should work with the talent they have got in front of them, not change them into something that we see in a coaching manual."

He added: "I hope Stuart sticks to his guns... and I hope the England set-up realise the talent they have and work with it."

Fast bowler Stuart, 20, made his debut for England in the one-day series against Pakistan this summer.

And he is determined to ensure he stays in peak condition in case he is needed against Australia.

"I wouldn't wish an injury on anyone and I want England to win the Ashes as much as anyone else," he said.

"But I'll keep myself fit and keep myself strong because an Ashes tour is a very hard tour.

"It's a three-month trip and the lads will do well to get through that unscathed."
