Firstly, enter the national support figures in the first line of the table below to set the overall national swing. Our current national support figures are shown, but you can override them. As you enter national support figures, the national trend values to the right will update.
Then, area-by-area, please enter the support for each party in each area. (Area definitions) This allows different areas to have different swings from the national trend. For reference, the national trend figures on the right give a helpful indication of the expected regional support if there were no differences in swing between areas. As a starting point, you can use the uniform national trend figures (press "Use Trend Values").
You can display just the seats predicted to change hands ("All GB changed seats"), or see a majority-sorted list of all GB seats ("All GB seats majority-sorted"), or study any area in detail. If a area is selected, the 'Individual seat' menu list allows you to see all the area's seats majority-sorted, or to examine a particular single constituency.
