'Most of all' or 'least of all'

[Sajumon]

Which is correct? I also want to know whether semicolon is the right punctuation after "....like that".
I would never tolerate anyone speaking to me like that;most of all, my wife.
I would never tolerate anyone speaking to me like that;least of all, my wife.

An independent clause must follow a semicolon unless it is part of a list of items with internal commas.

Thank you, Mister Micawber.
And,are both the sentences correct?If so, what is the difference in the meaning of the sentences?

[Mister Micawber]

When I read them to myself, both seem possible. The first ('most of all') refers to 'anyone' and the second ('least of all') refers to 'tolerate'. The second is probably the expected.
