England captain Alastair Cook is adamant his premier pace bowler James Anderson must stay true to himself "in the heat of battle", despite the allegations made against him by India.
The tourists have sent a Level 3 charge - one which brings with it a ban of up to four Tests, if proven - over Anderson's altercation with all-rounder Ravindra Jadeja as the teams made their way off for lunch on day two of the first match in the Investec series at Trent Bridge.
Subsequently, as the England and Wales Cricket Board had promised, the home team's manager Phil Neale sent a Level 2 counter-allegation against Jadeja.
Cook acknowledges exemplary standards of behaviour are non-negotiable for his team.
But he will not be asking Anderson to tone down his aggression on the field, because he believes that is when England's linchpin seam-and-swing bowler is at his best.
"No, I don't think I will," said Cook.
"We have a responsibility, as England players, never to cross that line. In the heat of the battle, when the emotion is up, there have probably been situations throughout everyone's careers when they've probably looked back and thought 'I wish I hadn't done that'.
"I don't think this is a case (like that)."
Accordingly, he will be telling Anderson to change nothing.
"I like it when Jimmy's in that battle, because I know he's up for it and desperate to do well for England," said the captain.
"When people are watching that, I think they get behind it and see a very competitive guy. I think people enjoy it."
England named an unchanged team at Lord's, and will bowl first after Cook won the toss on a sunny morning.
