Nevertheless, Hawke was able to comfortably maintain a lead as preferred Prime Minister in the vast majority of opinion polls carried out throughout his time in office. After leading Labor to a comfortable victory in the snap 1984 election, called in order to bring the mandate of the House of Representatives back in line with the Senate, Hawke was able to secure an unprecedented third consecutive term for Labor with a landslide victory in the double dissolution election of 1987. Hawke was subsequently able to lead the nation in the Bicentennial celebrations of 1988, culminating with him welcoming Queen Elizabeth II to open the newly constructed Parliament House.
