Mileage and business travel exp. in the same time

Can I book business travel expenses and mileage in the same time? A company employee went on a business travel to Paris. He travelled from his place of residence to Paris by private car. Can he account for mileage and business travel expenses at the same time?

Hi,

You will need to review the guidance here - 

EIM31800 - Deductions: travel expenses: general: contents

to determine if travel/accommodation expenses can be claimed.

Thank you
