[1][2] Alli served as the Chief Executive of Silvergate Media until 2022,[3] Chairman of Koovs Plc and a director at Olga Productions.

He is a member of the House of Lords in the United Kingdom, sitting as a life peer for the Labour Party, and is described as one of only a few openly gay Muslim politicians in the world.

[12] Alli is one of a group of prominent Guyanese people in Britain, which includes Raj Persaud, Herman Ouseley, David Dabydeen, Cynthia Pine, Keith Waithe and Rudolph Dunbar.

[13] Alli started work as a junior researcher for a finance magazine, crediting his first success to Salem Ghayar, who hired and mentored him.

Carlton Television bought Planet 24 in March 1999 for £15 million, with Alli and Parsons retaining the rights to the lucrative Survivor format.

[22] The sale helped to finance Alli's new company, Silvergate Media, and its purchase of the rights to Beatrix Potter and Octonauts from Chorion.

[23] He was part of a failed £100m bid backed by private equity firm 3i to buy Virgin Radio from SMG plc in 2005.

[27] Prime Minister Blair used him for years as a means to help him reach out to a younger generation (aka "youth subculture").

[15] He maintains ties with his Caribbean roots, both with other British-Guyanese politicians such as Valerie Amos and Trevor Phillips, and with President Bharrat Jagdeo.

[32] He advocated lowering the age of consent for homosexuals from 18 to 16, equal to heterosexuals; this eventually became law as the Sexual Offences (Amendment) Act 2000.

"[15][33] In 2006, he participated in the International Conference on LGBT Human Rights adopting the Declaration of Montreal and in 2009, he spearheaded an effort to repeal clauses in the Civil Partnership Act 2004 which prohibited religious institutions from conducting the ceremonies on their premises.

[42] The Telegraph also reported that Deputy Prime Minister Angela Rayner faced an investigation by the parliamentary standards commissioner over the use of Alli's $2.5-million New York apartment.

In 2002 he became a patron of The Albert Kennedy Trust, stating: "Being a teenager isn't easy and it's particularly difficult for vulnerable and socially excluded members of our community.

My first task as Patron will be to support plans to extend these services across the UK, to help the increasing number of young people contacting the Trust."
