How to delete all lines before a particular pattern when the pattern is defined in a variable?

I have a file

Code:
Line 1 a
Line 22
Line 33
Line 1 b
Line 22
Line 1 c
Line 4
Line 5

I want to delete all lines before last occurrence of a line which contains something which is defined in a variable. Say a variable var contains 'Line 1', then I need the following in the output.

Code:
Line 4
Line 5
