Using the general election results from 2019, this is what the 2021 Welsh Senedd election would look like if it had the same results as 2019. Labour would have won 29 seats, the same amount they have now, the Conservatives would have won 24 seats, an increase of 13, Plaid Cymru would have won 5, a decrease of 5, the Lib Dems would have won 1 (no change) and the Brexit Party would have won only 1 of their 4 seats.
