A TOP councillor faces an inquiry over claims that he made racially inflammatory remarks at a meeting in Huddersfield Town Hall.
Tories have protested over comments made by Clr Mehboob Khan, leader of Kirklees Council's Labour group.
Their complaints were sparked after he hit out at the failure by Liberal Democrats to include Asians in the council's new Cabinet.
Clr Khan told a council meeting: "It is sad that none of the Asian Liberal Democrats were considered to be of sufficient quality to be included in the Cabinet."
The Tories have reported him to the Standards Board for England, which watches over councillors' conduct.
Clr Robert Light, the Tory group leader, said the remarks were offensive.
"At best they were ill-informed and at worst they were racially divisive. They were completely unacceptable," he said.
Clr Light said his group had agreed there was no alternative but to report the Labour leader.
"We have also written to the Prime Minister questioning whether he considers this to be acceptable behaviour from a senior Labour Party member in such an important position," he said.
"Clr Khan's remarks have done nothing to promote racial harmony."
Clr Khan said he found it difficult to understand how his remarks had led to a complaint.
He attacked the Tory action as blatant political opportunism.
"The points that Clr Light takes issue with were just one part of wider points I was emphasising in relation to the Cabinet membership failing to reflect the council as a whole," he said.
"For example, six of the nine Cabinet members are from North Kirklees."
The Standards Board will weigh up the complaint before deciding whether to launch an inquiry.
A spokeswoman said: "We generally decide within 20 working days if a complaint is to be investigated."
