"Mae e'n mynd i Ffrainc a'r Alban."

Translation: He is going to France and Scotland.

Why is 'He is going to France and to Scotland' wrong?

[Jonlang_]

Mae e'n mynd He is going i Ffrainc to France a'r Alban and Scotland

There is no i between a and Yr Alban so it's not "and to Scotland", it's just "and Scotland".
