Tax implications from overseas bank account

[Crewcut]

Hi, I wonder if someone could advice me what would be best to do. I will in the next couple of months received a six figure sum from a good friend who has had a successful business deal in the Caribbean. I gave my friend a small amount of money to help them out no paperwork etc. Once they have been paid the money i can either have it placed in an overseas account where my friends money will be placed initially or I can have it sent direct to my UK account. I am retired and receive a small pension but I'm still in my late 50's so no state pension. What if any would be the tax implications on either of the options.

Thanks in advance for any advice.

If it's a gift then there are no UK tax implications. but it sounds more like a return on an investment.
Much more info required.

The money given was to assist with a legal matter but had no connection to the actual business transactions. This will be a gift to me and my family.
