Is zakat obligatory on every amount of money in the country where it is located (Britain and Libya), or on their total, and in which of the two currencies should this be done?

The zakat for each wealth should be disbursed in the country where it is located. Thus, what is in Britain has its zakat disbursed there, and what is in Libya has its zakat disbursed there. Ibn Qudamah said: "If a man is in one country and his wealth is in another, I prefer that it be paid where the wealth is located." In Kashshaf Al-Qina', it states: "Disburse the zakat for each wealth in its own country, so that charity is not transferred from the country of the wealth, and because wealth is the cause of zakat, it is obligatory to disburse it where the cause is found."
