Kuwait’s constitutional court on Sunday nullified last year’s legislative elections and ruled in favour of reinstating the previous parliament, state media said, as a political crisis roils the oil-rich Gulf state.

The September polls — the most inclusive in a decade — had seen opposition members clinch 28 out of 50 seats, giving them a parliamentary majority.

The vote marked a victory for opposition figures, many of whom had stayed out of elections in the past decade over what they saw as alleged meddling by the executive authorities over parliament.
