Pemimpin Oposisi (Britania Raya)

Di Britania Raya, Pemimpin Oposisi (secara resmi dikenal sebagai Pemimpin Oposisi Yang Mulia Ratu yang Paling Setia di Britania Raya(Leader of Her Majesty's Most Loyal Opposition in the United Kingdom)) adalah seorang politisi yang memimpin oposisi resmi. Terdapat pula seorang Pemimpin Oposisi di Majelis Tinggi (House of Lords). Akan tetapi, sejak Undang-undang Parlemen disahkan pada tahun 1911, tidak ada keraguan bahwa Pemimpin Oposisi di Majelis Rendah (House of Commons) lebih tinggi derajatnya dan memegang jabatan utama.

Sesuai dengan konvensi, Pemimpin Oposisi memimpin partai terbesar yang tidak berada di dalam pemerintahan. Jika partai pertama memenangi suara mayoritas pada pemilihan umum, maka pemimpin partai tersebut menjadi Perdana Menteri, sedangkan pemimpin partai terbesar kedua akan memegang jabatan Pemimpin Oposisi. Seorang Pemimpin Oposisi umumnya dianggap sebagai Perdana Menteri alternatif, dan duduk sebagai anggota Privy Council.

Pada abad ke-19, afiliasi terhadap partai tidak bersifat kaku dan pemimpin di kedua majelis memiliki status yang sederajat. Seorang Pemimpin Oposisi yang tunggal dapat terlihat dengan jelas hanya apabila ia merupakan Perdana Menteri yang selesai menjabat.

Pemimpin Oposisi memperoleh tambahan gaji di luar gajinya sebagai anggota Parlemen. Pada tahun 2010, tambahan gaji ini adalah senilai £73.617.

Pemimpin Oposisi di Britania Raya saat ini adalah Jeremy Corbyn dari Partai Buruh, yang menjabat sejak September 2015.
