regex of overlapping patterns

Question

I am trying to match all instances of the pattern in the string using Python. However, when the patterns overlap I get only the longest one, while I need both:

import re
st = '''GYMGMTPRLGLESLLEStopAS'''
w = re.findall("M\w*?(?=Stop)",st)
print w

Output:

1. MGMTPRLGLESLLE

Desired output:

1. MGMTPRLGLESLLE
2. MTPRLGLESLLE
