The phrase "wert in power" is an archaic version of "were in power." The word "were" is pronounced /wə(r)/ in IPA phonetic transcription, which is similar to how it is spelled. However, in older English, the past tense of the verb "to be" was spelled as "wert." The "w" is pronounced as /w/ and the "ert" is pronounced as /ərt/. Therefore, "wert in power" is pronounced as /wərt ɪn paʊə(r)/ in IPA phonetic transcription.
