Blaming Pakistan President Pervez Musharraf and MQM leader Altaf Husain for the violence in Karachi, cricketer-turned-politician Imran Khan has said he would file a case against British Prime Minister Tony Blair for harbouring Hussain, who lives in London in self-exile.

Imran, who heads the Therik-e-Insaf, told reporters in Lahore that he would file a case in UK against Blair for harbouring Husain, who, he said was head of a fascist organisation and lived like a king in London through the money sent to him from Pakistan.

Imran, a fierce critic of Musharraf has aligned with the Jamat-i-Islami (JI), which also is one of the political rivals of MQM.

More than 40 people were killed in violence in Karachi last week that was sparked off after the arrival of suspended Chief Justice Iftikar M Chaudhry.

The opposition parties squarely blamed MQM, which held a rally opposing Chaudhry's visit to Karachi for the violence.

The MQM, in turn, blamed the opposition parties for sparking off violence.

"MQM is a fascist organisation like Hitler's Nazi Party. No body dared to challenge the Nazi Party because it got its opponents eliminated," Dawn quoted him as saying.

"The MQM first fired bullets on the people and then tried to portray itself as a victim," he said adding instead of taking steps for maintaining law and order in Karachi, it got the MQM rally arranged intentionally to sabotage the reception of Chaudhry".

He said Musharraf was not tired of talking about enlightened moderation on the one hand and had joined hands with top terrorist Hussain on the other for remaining in power.
