Earth Summit, the 7-1 favourite, won the 1998 Grand National at Aintree giving jockey Carl Llewellyn his second victory after previously winning on Party Politics in 1992.

The weather had a big impact on the 1998 National making it exceptionally difficult for spectators who had endured long queues to get into Aintree due to the increased levels of security following the previous year’s IRA bomb alert.

Torrential rain had also turned the going to soft, heavy in places making it only the fifth National since 1977 to have been run on truly soft ground.

Earth Summit pulled clearahead of Suny Bay before the second last, running on to win the biggest horse race in the world by eleven lengths and making him the only horse in history that has ever won the Aintree Grand National and the Scottish and Welsh equivalents.
