Sack the lot of them, let civil servants run the day to day, pick the best lawyers to write laws, have a direct democracy to vote on them (as well as subsequent review votes).
People shit on direct democracy as if it is doomed to fail, and point to things like Brexit as an example of how it won't work. However, Brexit was a one off vote that had a huge disinformation campaign behind it, and such a campaign cannot be sustained indefinitely for everything. Also, many of the bad votes are basically joke votes; the novelty will quickly wear off when people start seeing that their vote has a direct result.
Long gone are the days where we need to pick someone to go to a central place of governance on our behalf. We pretty much all have the ability to communicate instantly across the entire nation and beyond. Why should we have a "representative" when they don't actually represent our views?
