The comedian was investigated by police in June 2019 after making a gag about throwing battery acid at politicians. Here's what you need to know...

Who is Jo Brand, how old is she and what's her background?

Jo Brand is a comedian and TV personality known for her dry sense of humour.

She was born in Wandsworth, London, in July 1957 and grew up in a small village in Kent.

Brand, 62, was a rebellious teen and was eventually kicked out of her family home by her parents.

The counter-cultural menace was persuaded by agent Malcolm Hardee to begin a career in stand-up comedy in the early 1980s, and acquired the stage name "sea monster".

In 1993, Brand transitioned into mainstream television and became a resident panellist on BBC comedy panel show the Brain Drain.

Since then her TV career has continued to blossom and she's won four British Comedy Awards and a Bafta for her sitcom Getting On.

If that wasn't enough, Brand became an unlikely fitness hero when she completed a 150-mile coast walk for Sport Relief in 2016.

Jo also worked as a nursing assistant for ten years in a residential unit for adults with learning difficulties.

In July 2007, Brand was awarded an honorary doctorate for her work as a psychiatric nurse from the University of South Wales.

Who is Jo Brand's husband Bernie Bourke?

Jo has been married to her husband Bernie Bourke since 1997 and the pair have two daughters, Maisie and Eliza.

The pair met at a comedy show when Jo was 38, and Bernie is six years younger than his famous wife.

Unlike many celebrity spouses, Bernie is not in showbiz as he works as a psychiatric nurse at a hospital in London.

The couple do have a lot in common, however, because Jo was a psychiatric nurse herself before becoming a comic.

Why was Jo Brand being investigated by the police?

Cops launched a probe into left-wing comic Jo Brand after she joked Nigel Farage should be doused in battery acid rather than milkshake.

The Met Police said it received an allegation of "incitement to violence" after Brand joked about attacking politicians on Radio 4 show Heresy.

Brand apologised before appearing to back-track as broadcasting watchdog Ofcom said the number of complaints had soared from 19 to 65.

The Metropolitan Police has said it will take no further action over Brand's comments.

The BBC initially defended airing the remark, saying: "Panellists often say things which are deliberately provocative and go against societal norms but are not intended to be taken seriously."

However, the broadcaster said it would edit the joke from the show, despite wanting to promote comedy that "pushes boundaries".

On June 14, the episode was unavailable on its website and BBC Sounds app.

It is understood Brand will continue to work for the BBC, with police saying there will be no further action.

The comedian made a half-hearted apology in June 2019.

What TV shows has Jo Brand presented?

Jo Brand is a regular guest host on BBC quiz Have I Got News For You.

The funnywoman has hosted her own 90s programmes, Jo Brand's Big Splash and Jo Brand Through The Cakehole.

But her proudest telly achievements are arguably her sitcoms Getting On, set in an NHS geriatric ward and directed by Peter Capaldi, and Damned, set in a Social Services office.

She's the host of The Great British Bake Off spin-off show on Channel 4, after hosting The Great British Bake Off: An Extra Slice on BBC.

In 2019, she's one of the comedians doing silly tasks for the Taskmaster in series nine.

The small screen seems to be just too small for Jo now though, as she's also set to star in her own adaptation of her novel The More You Ignore Me, alongside Sheridan Smith and Sheila Hancock.

It's said to be about "Mental illness, Morrissey and guinea pigs" and is set for release later in 2017.
