Italy won the 2006 FIFA World Cup. Two months prior to that Romano Prodi's party won 348 seats to 281 for the coalition led by Silvio Berlusconi. Two years later Berlusconi won 344 seats and the Government. So zero out of two.
Of course in these cases the elections were held some time after the sporting victory. There doesn't appear to have been a situation where a country has hosted or won a FIFA World Cup just before an election, as is happening in New Zealand with the Rugby World Cup.
The more likely impact of the Rugby World Cup is that it will reduce the ability of politicians to get headlines. This would be bad for the Government if they were behind in the polls, but could work out well for them as they have such a commanding lead.
Parliament will sit for the last time on Thursday 6 October. Two days later we will have the quarter-finals.
On the 20th of October the Governor-General will send a lackey to the forecourt of Parliament reading out a proclamation dissolving Parliament. The next day will see the play-off for third and fourth place.
On Sunday the 23rd of October the nation will watch the final, and half the country will turn up to work on Monday late and with a hangover. The hangovers should have worn off enough that by the end of the week voters may want to start listening to the politicians again.
By then, there will be just four weeks to go before the election on 26 November. Will that be enough time to close a 25 per cent gap? Labour may be regretting, with hindsight, deciding to hold the Cup so close to an election.
