MCA publicity bureau deputy chairperson Lau Chin Kok said some Umno members are partly responsible for the low non-Malay support for BN.
"The low non-Malay support towards BN is attributed to many factors.
"It may be partly due to the provocative remarks and threats hurled by a small group of Umno members, which repeatedly tarnished the image of BN," he said in a statement today.
Lau said this in response to Federal Territories Minister Tengku Adnan Tengku Mansor, who is also Umno secretary general, urging Umno's partners to "wake up" and help muster support for BN.
"MCA has not only started preparing for the general election, but has been actively reaching out to the voters.
"Instead, a small group of ‘troublemakers’ in Umno still live in their own world and continue to dismiss outside voices."
Lau said Tengku Adnan should not dump the responsibility on other BN component parties.
He added BN component parties should not be blaming each other which opens them up to opposition attacks.
"Tengku Adnan should interact more with the component party members, as to understand the challenges faced by each of them, as well as to strengthen the mutual trust among the component parties and punish those who attempt to destroy the BN spirit," he said.
MCA has not been able to capture a single seat in the federal territories since the 2008 general election.
Umno, which only won one parliamentary seat in Kuala Lumpur in the 2008 election managed to increase it to two in the 2013 General Election.
They are the parliamentary seats of Setiawangsa and Titiwangsa. - Mkini
