It is the current governing party, having won the 2019 general election, and has been the primary governing party in the United Kingdom since 2010. The party sits on the right-wing to centre-right of the political spectrum. It encompasses various ideological factions including one-nation conservatives, Thatcherites, and traditionalist conservatives. The party holds the annual Conservative Party Conference, at which senior Conservative figures promote party policy.
