The Union of DP Members and Supporters yesterday announced at a press conference that it had submitted an urgent note to Prime Minister S.Batbold, reaffirming the Constitutional rights of residents of ger districts to live and to study in a healthy and safe environment. The organization had earlier demanded free two-room apartments for all households in ger districts, the money to come from the mining revenue. It now demands that the Prime Minister should take a decision to this effect by June 9, failing which he should resign.
