premise: Four members of Bangladesh's interim government quit on Monday in protest at the president's decision to deploy the army to restore order ahead of January's elections.
  The resignations came despite assurances from President Iajuddin Ahmed that calling in the military would not harm the democratic process in the country, paralysed for weeks by opposition protests and bloody clashes.
  "We have sent our resignation letter to the president, because we think that no situation has been created in the country that warranted an army deployment," interim cabinet member Sultana Kamal said.
  The president ordered the deployment late on Saturday in a bid to restore order and counter opposition threats to conduct non-stop protests to force electoral reforms.
  The opposition, led by the Awami League, have alleged the January 23 polls will be rigged in favour of the outgoing Bangladesh National Party (BNP).
   Why did four members of Bangladesh's interim government quit?
