Claim Remittance Basis for Foreign Capital Gain and Foreign Income

Dear Sir/Madam. I am UK resident but non-domicile UK as I only live in UK for 2 years since born. I have foreign capital gain for oversea property sold and foreign bank saving interest income. I choose remittance basis which mean I will not remit above foreign capital gain and foreign income to UK. The question is : Do I need to fill SA108 (Capital Gains Tax summary) and SA106 (Foreign)? Do I need to show the detail calculation on how to come up to the figure ( Capital Gain) like Sale-Purchase Price - (LET) or just give the lump sum figure of capital gain? Regards, FO
