Do you have a revocation clause precedent that does not revoke any future potential foreign Wills that may be made in the future by the testator?

A revocation clause in an English Will generally only takes effect to revoke any existing (ie, previous) Wills made by the testator. Revocation clauses may be limited so as to not revoke a particular earlier Will or a Will covering specific assets, such as a foreign law Will.

As a matter of English law, a Will is revocable at any time during the testator's lifetime. A Will may only be revoked by automatic operation of law (involuntary revocation) or by a deliberate act of the testator (voluntary revocation). Apart from these methods, and where there has been an obliteration under section 21 of the Wills Act 1837 (WA 1837), an attempt to revoke the Will by any other method will be ineffective.
