On 13 December 2007, during her appearance on the TV show Never Mind the Buzzcocks (which was hosted at the time by Simon Amstell), Oliver implied that she was sacked from BBC Radio One following a comment she made in an interview with NME magazine, about Fearne Cotton, calling her a "Devil Woman".
Oliver made a brief appearance in May 2007 on the BBC programme Neneh & Andi Dish It Up – which is presented by her mother Andrea and "Auntie" Neneh Cherry – and has also made appearances on political talk show This Week, on 25 June 2009 and 17 December 2009.
She continued to present programmes for T4, such as T4 Movie Special in August 2011.
In November 2011, Oliver filed for bankruptcy after non-payment of a tax bill.
In March 2010 Oliver made a programme for Channel 4's T4 called "Miquita's Oliver". The finished product was performed at the Hackney Empire to surprising critical acclaim.
She was set the challenge of starting a one-off urban production of the classic musical Oliver! She then went on to have her own television show, called The Month With Miquita, which she hosted on the 4Music channel.
