The rupee hit a record low of 180.85 per dollar on Wednesday, surpassing its previous low of 180.50 hit on Tuesday.

The political standoff took another turn on Thursday as the parliament cut the budget of the Prime Minister's office, a move designed to hinder disputed premier Mahinda Rajapaksa whose supporters boycotted the vote in the latest twist in a weeks-long political stalemate.

The new government has not been recognised by any foreign countries because they have not proven their parliament majority.  ** The political paralysis remains the main concern of investors. While Rajapaksa and President Maithripala Sirisena have failed to win support in parliament for their new government, the deposed prime minister Ranil Wickremesinghe's coalition, which claims it does have majority support in parliament, has not been allowed to try to form a government.

The political impasse could be set to drag on longer after President Sirisena said on Sunday he would not reinstate Wickremesinghe as prime minister even if he was able to prove his majority in parliament.
