Time expressions: NEXT and LAST

Hi! I have a question about time expressions.

Right now, it’s October 2008.
If I say “I went to London LAST JUNE” would I mean June 2008 or June 2007?
Would it be correct to say “I went to London this June” if I meant June 2008?

Similarly, lets pretend it’s Monday today. if I said “I’ll call you next Tuesday” would I mean Tuesday TOMORROW or Tuesday seven days from now?

Please help, I can’t find the answer anywhere!
