In the 1991 by-election to the Gibraltar House of Assembly, following the resignation of GSD Leader
Peter Montegriffo,
Peter Caruana was elected party leader and won 61.81% of the popular vote to fill in the vacant seat. In the
1992 election, the party won 20.20% of the popular vote and 7 seats. In the
1996 election, the party won 52.20% of the popular vote and 8 seats. In the
2000 election, the party won 58.35% of the popular vote and 8 seats. In the
2003 election, the party won 51.45% of the popular vote and 8 seats. In the
2007 election to the newly named (and reorganised)
Gibraltar Parliament, the party won 49.33% of the popular vote and 10 seats. In the
2011 election, the party won 46.76% of the popular vote and 7 seats, unable to secure a fifth term. In the
2013 by-election, the GSD candidate
Marlene Hassan Nahon won 39.95% of the popular vote. In the
2015 election, the party won 31.56% of the popular vote and 7 seats. The GSD endorsed the
Conservative Party in the
2015 British general election. In the
2019 election, the party won 25.60% of the popular vote. However they lost 1 seat down from 7 to 6 MPs. This resulted in the Party's MP and Shadow Minister, Trevor Hammond, to be unseated and to be taken by
Marlene Hassan-Nahon, who recently formed and lead her own progressive party,
Together Gibraltar, during the elections. In the heavily contested
2023 election, the party won 48.15% of the popular vote. They gained 2 more seats, rising 6 to 8, thus returning to become Gibraltar's sole Opposition Party since 2015 (1 seat from the sole TG MP, Marlene Hassan Nahon, who announced a couple months before that she wasn't seeking re-election and was retiring from politics; and the other from The
Alliance's new MP, Vijay Daryanani ((
LPG)) ). Two of their new 2023 candidates, Youseff El Hana (who became Gibraltar's first political candidate from the local Muslim/Moroccan community) & Daniela Tilbury received controversy from their past ordeals during the elections. Both of them were polled low and were not elected into Parliament as a result Youseff's past social media posts from 2018 gained controversy due to them being seen as "antisemitic" for his references of his support for Palestine for the ongoing decades-long internal and religious conflicts between them and Israel. He apologised for offending the local Jewish community on GBC News during the election campaign but denied the accusations of him attending an anti-semitic Palestinian march. Daniella Tilbury also received controversy due to her past allegations of bullying her staff and students during her chair and executive roles at the University of Gibraltar, resulting for her to resign from her posts. No formal apology was made during her campaign. After the General Elections, there was the party’s leadership elections between the incumbent Party and Opposition Leader, Keith Azopardi and his colleague, Damon Bossino, who was appointed Shadow Minister for Housing, Lands & Transport. The former identifies himself as a centrist and progressive GSD MP whilst the latter identifies as a more conservative figure. On December, the results were in favour of Azopardi with 58% compared to his opponent with 42%. ==Election results==
