Alex Lester (born Alexander Norman Charles Lester; 11 May 1956 in Walsall, England) is a British broadcaster. He presented the weekday overnight/early-morning programme on BBC Radio 2 from 1990 until 2014. From October 2014 until January 2017, he presented the midnight to 3.00am programme every Friday, Saturday and Sunday. He also temporarily replaced Russell Brand on Saturday evenings in late 2008, between 9 and 11pm, following Brand's resignation over his infamous prank calls row.
A doctor's son, Lester was educated at Denstone College, and worked in a variety of jobs (including at Dudley Zoo, in a pub, and as a civil service clerk), before he began his broadcasting career in 1977 for BBC local radio stations. He joined Radio Aire in Leeds in 1981.
Later, he worked for other radio stations in the commercial sector. These included Radio Tees, based in , where he worked from 1983 until 1986. At Radio Tees, on joining, he narrowly avoided an attempt by Canadian programme controller Donald Cline to rechristen him "Red" Lester. Lester went on to present, amongst others, the weekday lunchtime show and a specialist blues music programme there.
In 1986 he returned to the BBC, presenting the breakfast show (indeed, the first show) on the newly opened BBC Essex based in Chelmsford. Lester joined Radio 2 in 1987 as an announcer and newsreader. He also presented the night-time show on a rota basis. In 1990 he was given the early-morning show permanently.
Lester kept UK truckers and other night-shift workers awake with his weird and strange observations. The meaningless but catchy show slogans are SCOF (Swirling Cesspool Of Filth) and Slap My Top (thought to be a variation on the music hall soundbite slap my thigh – but reserved exclusively for people with bald heads) and listeners have marketed the show by writing the phrase in the dirt on the backs of trucks and vans. There was a limited edition range of T-shirts with the slogan written in Cantonese developed by a listener, which Lester awarded to people who came up with the most innovative uses of the slogan – winners included a local radio reporter who got the expression into a story; a man who wrote and recorded a song with the slogan as its title; a mystery girl, for placing an ad for Lester's show in the small ads section of a local newspaper and a man who developed a website which remains a communal meeting point for the programme's listeners, and is listed in the External Links section below. As well as T-Shirts another listener produced a range of glow in the dark Alex Lester wristbands which were also given away as prizes on the show. The new phrase for the 2010–2011 Truck Writing Season was WALLOP (We're Alex Lester's Lovely Overnight People), and in 2013 the slogan ALAN was introduced (Alex Lester At Night).
