Labour members of the UK House of Lords narrowly failed to delay the bill to call a referendum on the Alternative Vote for May, 2011. The vote was 224-210 to reject a proposal to refer the bill to a committee for further discussion (i.e. stalling).
The bill would set the referendum for the same date as the elections for the Scottish Parliament, Welsh Assembly, and some local councils. Labour opposition stems largely from the linkage of the AV referendum to a review of constituency boundaries, which currently favor Labour.
