POV ==

The comments at the end of the article violate the Wikipedia policies on NPOV and verifiability.  In particular:

"But the party never succeeded in persuading many people that Communism was the answer to these problems." -
This statement implies that the CPA was trying to persuade people that Communism was the answer to issues of civil rights, etc.  I doubt that this is the case, and it is not supported by any source that I know of.

"Against these achievements must be set the party's long history as an apologist for the Soviet Union." -
The word "apologist" is highly pejorative, and has no place in an encyclopedia article.  For example, the article on the Liberal Party does not describe them as an apologist for the United States.  In addition, the CPA appears to have been critical of the Soviet Union starting in 1968 (23 years before its dissolution).  It would be reasonable to state that the CPA long supported the Soviet Union, but this would be misleading without mentioning that the party was later critical of the Soviet Union.

"Disenchantment with the Soviet Union led most of the party's members to leave over time." -
There were many factors leading to declining membership, and some people even left due to the CPA's criticism of the Soviet Union.  Although it is likely that disenchantment with the Soviet Union was the primary cause, this statement should be more specific and supported by a source.

Giving positive and negative POV is different to NPOV.  The article should present facts without passing moral judgement.  On its own, listing the issues that the CPA campaigned on is not POV, because it does not pass moral judgement on whether these were good or bad (although the wording does tend to present these campaigns as positive).  However, using the wording "Against these achievements must be set" turns the paragraph into an argument on the merits of the CPA, with the campaigns presented as something positive and support for the Soviet Union presented as something negative.
TABIf this material is included, it should be given in a separate paragraph and give a factual account of the CPA's history of support and criticism of the Soviet Union.
