If you have ever wanted to be like BBC TV election pundit Peter Snow and try to predict the outcome of the election, now is your chance.
Enter each party's share of the vote in the boxes below, click the Go button and the program will calculate how the new UK Members of the European Parliament might line up.
Please note that this is not a BBC forecast, nor is it meant to be anything other than an interesting exercise. Your attention is drawn to the points below.
Be advised that the share of the vote must be for Great Britain as a whole - Northern Ireland is not included because of its different electoral conditions. In addition, do not put in the level of support the SNP or Plaid Cymru would get just within Scotland or Wales respectively, as this would give incorrect results.
If you do not enter a figure for Others then the program will assume that any percentage left over out of 100 is the value for these parties.
In addition, please note that Others are considered by the model to be a single party. This is a simplification and will give improbable results at high percentages, but is necessary to make the program simple to comprehend.
