A few tricky clues this week but I've finished it, however, could somebody help me grasp the wordplay on this one.
6a) Free to tell one about Dag Hammarskjold (5)
I have U - G - G.
I'm sure it's 'ungag'
Is it a double Def?
1st Def = free to tell (with 'free' being a verb) - to ungag someone.
2nd Def = one about Dag Hammarskjold
Is this meaning that the 'one' is a joke (gag) about the United Nations because he was the UN Secretry General?
