This is regarding a forged Auditor-General's reported circulated on social media.
De Lille, who hung up her mayoral chain on October 31, said she would lay the charges at the Cape Town central police station on Thursday.
The social media post titled "Patricia de Lille exposed" purports to be a document of the Auditor-General Kimi Makwetu with his signature attached, and lists a number of breaches by De Lille related to the MyCiti bus procurement process.
Makwetu later confirmed the document was fake.
De Lille initially threatened to sue the MPs if they did not apologise in public.
The two MPs are DA deputy chief whip Mike Waters and National Council of Provinces MP Bronwynn Engelbrecht.
