We can specify whether a party is a part of the government (or otherwise has control of the legislature if they hold a majority of seats) in our visualization by using geom_highlight_government(). geom_highlight_government() surrounds the circle with an outline.

Although the primary purpose is to highlight members of a governing coalition, this function is not limited to highlighting governments. If, for example, you wish to highlight the Australian government's front branch, write
australia <- election_data %>%
filter(country == "Australia" &
house == "Representatives" &
year == 2016)
australia <- parliament_data(election_data = australia,
party_seats = australia$seats,
parl_rows = 4,
type = "horseshoe")
au <- ggplot(australia, aes(x, y, colour = party_short)) +
geom_parliament_seats() +
geom_highlight_government(row == 1 & government == 1) + # this highlights the front bench.
theme_ggparliament() +
labs(colour = NULL,
title = "Australian Parliament") +
scale_colour_manual(values = australia$colour,
limits = australia$party_short) +
theme(legend.position = 'bottom')
au
