Mr Cross, who is also the MDC-T's Policy Coordinator-General, earlier this week posted on his blog that Mr Tsvangirai was seriously ill and "might not be able to handle the election and subsequently the responsibility of being president of a country".
Mr Cross went on to reveal that Mr Tsvangirai was in a financial crisis.
Addressing journalists at a media conference in the capital yesterday, MDC spokesperson Mr Obert Gutu rubbished Mr Cross' statements, saying they were made on a personal basis which was far from the party's position.
"I'm not going to even dignify the comments of the senior official because he was writing in his personal capacity. He has no mandate to speak on behalf of the president's family, he's not the presidential spokesperson," said Mr Gutu.
But Mr Gutu was not done yet as he went on to tear into Mr Cross' personality. Said Mr Gutu: "Not only is Honourable Cross a senior member but he's also an old man, old enough to be your father. So obviously the necessary processes will be instituted."
Mr Gutu put the likely punitive action to be taken against Mr Cross all bare when he said: "All of us have the duty to be disciplined. And especially when you're talking about matters to do with personal issues, no one has a mandate to talk about the state of anyone's health because there's an issue of confidentiality."
Mr Gutu reiterated that Mr Tsvangirai was recovering well and is expected back into the country in the few coming days following his recent trip to South Africa where he is recieving medical attention.
Mr Tsvangirai has since taken an indefinite leave and given the mandate to run the party to his three deputies Mr Nelson Chamisa, Engineer Elias Mudzuri and Dr Thokozani Khupe.
Bitter exchange of words and verbal fights have characterised the MDC-T house since Mr Tsvangirai's disclosure that he was diagnosed of cancer of the colon last year, with senior members being at each other's throats as they jostle for leadership positions.
