Chad parliament approves new constitution expanding president's powers

I think there may be some confusion here.

Chad is a country in Central Africa, and it does not have a "Parliament" in the classical sense. Instead, it has a National Assembly, which is a unicameral legislature composed of 188 members elected by proportional representation.

Additionally, Chad has a presidential system of government, where the President serves as both the head of state and the head of government. The President is elected by popular vote for a five-year term, and is limited to two terms.

It's possible that you may be referring to a specific news article or report about Chad, but without more context, it's difficult to say for certain what you're referring to.

If you could provide more information or clarify what you're referring to, I'd be happy to try and help you further!
