Is the part in bold correct?

EDITED

There are two Chee Soon Juans.
The first is the law-breaking, minister-heckling, hunger-striking attention seeker who is more interested in promoting a ‘Western’ form of democracy ill-suited to our Asian society than in bread and butter issues. He is one of the two ‘duds’ the Minister Mentor mentioned as the sort of people he had prevented from entering parliament. (The other being J.B. Jeyaretnam.) This is the version which, if you believe Dr Chee, is the one that the mainstream media often portrays, and which the public buys.

Is the part in brackets with "The" in upper case coupled with a partial sentence correct?

Thanks.

Could someone please help? Thanks.

I would prefer something like this:

"He is one of the two ‘duds’ the Minister Mentor mentioned as the sort of people he had prevented from entering parliament, the other being J.B. Jeyaretnam."

It’s perfectly OK to use parenthetical sentences, phrases or words to add information to the previous sentence. The info within the brackets can be deleted without losing the main meaning.

So, what part is in bold, again?

In parentheses, actually.
