The Tanganyika-Zanzibar Union remains a thorny political marriage. After failing to address the imbalances of the Union during the constitutional process (2011-2014), the fissures that characterize the Union have further increased. Chadema's luminary Tundu Lissu who is also the MP for Singida East has blown the lid off by claiming that Zanzibar is a colony of Tanganyika. Tanzania Mainland has been used wrongly to refer to Tanganyika - which the Warioba led Constitutional Review Commission recommended its reintroduction. Speaking in Zanzibar during a CUF campaign rally for the Dimani by-election on 11 January, 2017, Tundu remarked:
"Makoloni yananyonywa kiuchumi, yanakandamizwa kisiasa na yanatawaliwa kijeshi. Zanzibar ni koloni la Tanganyika kwa kivuli cha Tanzania."
Below is a translation of his assertion:
"Colonies are economically suppressed, politically suppressed and governed militarily. Zanzibar is a colony of Tanganyika under the guise of Tanzania"
