The party participated to the 1989 European Parliament election as part of the coalition Lega Lombarda – Alleanza Nord.

In February 1991 it was one of the founding members of Lega Nord, taking the current name, and since then it has been the "national" section of that party in Liguria.

[2][3] The LNL has also been represented in Silvio Berlusconi's governments by Sergio Cappelli (1994–1995), Balocchi (2001–2006, 2008–2010), Belsito (2010–2012) and Sonia Viale (2010–2012).

Over the years, the party suffered several splits, including one led by Ravera, who was welcomed back in 1998 and appointed "president for life".

[10] In fact, the LNL had renounced to run its own candidate, Edoardo Rixi, in favour of Toti[11] and won almost twice the votes of Forza Italia in the election itself.

The party is usually stronger in the western part of the region, indeed in 2015 it got 22.7% of the vote in the Province of Imperia, 24.4% in Savona, 18.7% in Genoa and 18.5% in La Spezia.
