Parliament voted on whether to launch a formal inquiry into whether Prime Minister Keir Starmer misled the House of Commons over his handling of Peter Mandelson's security vetting process. The BBC's Politics section has now published a searchable tool allowing constituents to track how their individual MPs voted on the motion.

The inquiry centers on allegations that Starmer failed to disclose details about Mandelson's vetting when appointing him as a senior advisor. The vote itself became a test of party discipline and public confidence in the government's transparency. MPs had to choose between backing an investigation or defending the Prime Minister's account.

The BBC's voting tracker breaks down results by constituency and party affiliation, making it easy for voters to see whether their representatives supported scrutiny of Starmer or sided with the government. This kind of transparency tool has become standard practice for major parliamentary votes, helping citizens hold legislators accountable between elections.

The Mandelson vetting controversy has dominated Westminster debate in recent weeks, raising questions about ministerial oversight and whether proper procedures were followed during the appointment process. The vote's outcome and individual MP positions may shape public perception of the government's commitment to accountability.

THE TAKEAWAY: How MPs voted on Mandelson inquiry became a key measure of backbench willingness to challenge their own government on transparency grounds.
