WASHINGTON (Reuters) - Senate Majority Leader Harry Reid on Saturday delayed a test vote on the Democratic debt limit increase plan until 1 p.m. EDT Sunday to give negotiators more time to work out a deal.

In brief remarks on the Senate floor, Reid, a Democrat, said that negotiations between congressional leaders and the Obama administration were ongoing, but that there was "still a distance to go" before a deal might be reached.

The Senate had been scheduled to take a 1 a.m. EDT test vote on Sunday on the Democratic debt limit plan that Republicans said they opposed and could have blocked.
