The boundaries for many parliamentary constituencies have changed ahead of the upcoming general election.
Boundaries for each seat are reviewed periodically across the UK by the four Boundary Commissions in England, Scotland, Wales and Northern Ireland.
The most recent review was completed in 2023, meaning this is the first general election to be held with the new boundaries. A significant number of new seats have been created, while others no longer exist.
Analysis by ITV Calendar political correspondent Charanpreet Khaira
These new constituency boundaries were recommended by independent commissions - they weren't designed to benefit any one party over the others.
But there'll always be winners and losers, and the new boundaries mean that nationally, the Conservatives gain seven seats, while Labour loses two.
That might have worried Labour a few months ago, but now, with their lead in the polls soaring, it's unlikely to be keeping Sir Keir Starmer up at night.
As you can see from the map above, there are some significant changes in our region. The constituency of Pudsey has now disappeared, for example.
Pudsey is now part of the Leeds West and Pudsey constituency - so what was a Tory seat is now part of a wider constituency that's expected to go to Labour.
That prompted former Pudsey MP Stuart Andrew, who's also a Sports Minister in Rishi Sunak's Cabinet, to look elsewhere for a seat.
Cleethorpes has now been split up into Great Grimsby and Cleethorpes, and Brigg and Immingham.
That means an area that has consistently voted blue will be divided, with half going into the much more volatile seat - Great Grimsby and Cleethorpes.

It's also worth noting that some seats have changed hands since that 2019 result.
Wakefield had a by-election in 2022, triggered by the resignation of Tory MP Imran Ahmad Khan, and was won by Labour.
Selby too changed from blue to red in 2023, when the incumbent Nigel Adams, from the Conservative Party, stepped down. In March, the incumbent Tory MP for Ashfield switched over to Reform UK, giving them their first seat in Parliament.
All of this matters because we can only judge the scale of the victory for whoever takes the keys to Downing Street on 5 July by comparing to what came before.
This time around that's trickier, but the map above gives us a basis to plot out the change to the political landscape in our region.
On behalf of a number of news organisations - including ITV News - extensive research has been carried out estimating what the results of the last general election in 2019 would have been if the new seat boundaries had been used.
You can now explore those results for the Calendar region using the interactive map above.
