Senior Labour officials say talks with the third-place Liberal Democrats on forming Britain's next government are unraveling.

Labour's Health Secretary Andy Burnham signaled that his party's chance of sealing a pact were over -- meaning that Conservative Party leader David Cameron could become Britain's prime minister.

Prime Minister Gordon Brown's office declined to confirm that the chances of a deal were dead but said Brown had no plans to tender his government's resignation to Queen Elizabeth II on Tuesday.
