Uzbekistan is set to adopt a new constitution in a referendum on Sunday which could allow President Shavkat Mirziyoyev to extend his rule over Central Asia's most populous nation to 2040.
The 65-year-old leader's second term ends in 2026 and his move to circumvent term limits is likely to upset Uzbekistan's Western partners who have previously praised him for opening up the country's economy and promoting a relatively liberal political agenda.
