# Next UK by-election called by…?

Live · $445 traded · listed on Polymarket

## About

This market will resolve to "Yes" if a writ calling for a parliamentary by-election in a UK parliamentary constituency is issued by the UK Clerk of the Crown in Chancery by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No".

The issuance of a writ must be confirmed within the specified timeframe to qualify.

Only a writ issued after market creation will count. The writ for the Holborn and St Pancras by-election, issued prior to market creation, will not qualify.

The primary resolution source for this market will be official information from the government of the United Kingdom, including the UK Parliament and the relevant local government conducting the election; however a consensus of credible reporting will also be used.
