Mexico's constitution prevents any single party from being over-represented by more than 9 per cent. In order to secure a majority of 251 seats (out of 500) a party must have received at least 42 per cent of the vote. For the past two general elections - and in nearly 50 local ones - no serious irregularities have emerged, and all political parties now have fair access to the media, with an independent judiciary as the supreme electoral authority. The fruits of these reforms are there for all to see: over 35 million Mexicans live in states ruled by parties other than the one which has retained the majority at the national level, in clear recognition of local political trends.
I must also point out that the mayor of Mexico City has never been, as Mr Davison suggests, "hand-picked" by the ruling party. Indeed, the fact that the inhabitants of Mexico City are about to elect their Governor should confirm the depth of the reforms carried out under President Zedillo's administration.
