Our forecast model classifies seats in to four categories:

• Safe seats are very unlikely to be won by another party. Seats are considered safe if the model thinks they will be won by the same party at least 90% of the time.
• It is improbable that a likely seat is won by another party. Seats are considered likely if the model thinks they will be won by the same party at least 80% of the time.
• Seats that lean to one party may be won by another party. Seats are considered to lean to one party if the model thinks they will be won by the same party at least 70% of the time (or 60% of the time if three parties win 10% of the vote).
• All other seats are described as toss-ups.

The seats currently rated as a toss-up show where the battle lines are currently drawn. The tables below show which parties are competing to win each of the seats we currently forecast as a toss-up. Some seats are two way fights whilst others feature three parties.
