Sure, here is a Python solution for finding the longest palindromic substring in a given string:

```python
def longest_palindrome(s):
    def expand_around_center(s, left, right):
        while left >= 0 and right < len(s) and s[left] == s[right]:
            left -= 1
            right += 1
        return s[left + 1:right]

longest = ""
    for i in range(len(s)):
        # Find longest odd length palindrome with s[i] at its center
        palindrome_odd = expand_around_center(s, i, i)
        # Find longest even length palindrome with s[i] and s[i+1] at its center
        palindrome_even = expand_around_center(s, i, i + 1)
        # Update longest palindrome
        longest = max(longest, palindrome_odd, palindrome_even, key=len)

return longest
```

Here's how it works:

1. We iterate over each character in the string.
2. For each character, we expand around the center of the palindrome. There are two cases to consider: the length of the palindrome is odd (the center is the character itself), or
