Poland's lower house of parliament has rejected a motion to dissolve itself and pave the way for early parliamentary elections amid deep popular discontent with the ruling center-left party.

The dissolution motion failed to muster the necessary majority Thursday in the Sejm, or lower house. This means elections are still set for October when the lower house completes its term.
