Estate with two co executors, selling the estate property and CGT reporting

When the sale of the estate property generates a Capital Gain vs value provided by chartered surveyor for probate, should the two executors 1. Nominate one executor as the 'Personal representative' to report the Capital Gain to HMRC on behalf of the estate or 2. Do both executors need to report the capital gain to HMRC individually Thanks

For further clarification , the one of the coexecutors is a beneficiary of the will, the other coexecutor is a trustee for a trust which is the other beneficiary to the will. Look forward to reply

Hi,
If the terms of the will have specified 2 executors/beneficiaries then both need to report their own share.
Thank you.
