Parliamentary Under-Secretary (Department for Transport)
Labour MP for Selby
MPs have many roles, but one of the most important is that they make decisions. These decisions shape the laws that govern us, and can affect every aspect of how we live our lives. One of the ways MPs make decisions is by voting.
On TheyWorkForYou, we create voting summaries that group a set of decisions together, show how an MP has generally voted on a set of related votes, and if they differ from their party.
You can read more about our process, the kinds of votes we include, how we compare MPs to parties, and why we think this is important.

All MPs could vote remotely through an online voting tool. Votes cast remotely are shown as normal on the TheyWorkForYou voting record.
The option of online voting was removed, and a number of MPs may have been unable to vote because they were not physically able to attend.
The requirements on proxy voting were relaxed, allowing MPs to designate another MP to cast a vote on their behalf.
If an MP votes by proxy, it is effectively exactly the same as if they cast the vote in person and it shows up on their TheyWorkForYou voting record.
MPs are not required to designate a proxy, and may instead pair with an opposing MP to miss a vote. Parliament does not record when two MPs have come to a pairing arrangement, so on TheyWorkForYou, they will both appear to have been absent for the vote.
