Okay, the user wants me to translate "lech walesa" into Thai. Let me check if this is a proper noun. Lech Wałęsa is a well-known Polish politician, former president, and leader of the Solidarity movement. His name is a proper noun, so it's likely that the translation should keep the name as is but possibly with Thai script transliteration.
First, I need to confirm if the user expects a direct translation or transliteration. Since names of people are usually transliterated rather than translated, I should convert "Lech Wałęsa" into Thai characters. The standard way to transliterate names into Thai is using the Thai alphabet to approximate the pronunciation.
Breaking down "Lech" and "Wałęsa". "Lech" would be ลีช in Thai. "Wałęsa" might be written as วัลเเลสซา or วัลเลสซา. I need to check the common transliteration for his name in Thai sources. Sometimes, the 'ł' in Wałęsa is pronounced as a soft 'w' sound, so it might be written as วัลเลสซา.
I should also consider if there's an official Thai spelling for his name. If not, using the closest approximation is acceptable. So the full name in Thai would be ลีช วัลเลสซา. I'll make sure there are no typos and that the transliteration follows standard Thai pronunciation rules. Since the user specified to provide only the translation result without explanations, I'll present it as such.
