The incoming Home Office minister Lynne Featherstone has said she is happy with her appointment as Norman Baker's replacement and is looking forward to resuming her work on women's rights, including bringing an end to female genital mutilation.
I am very happy to be returning to the Home Office. I am very proud of what I was able to achieve in my previous role there, not least introducing equal marriage, ending the fingerprinting of children and banning wheel clamping on private land.
I am also looking forward to continuing my work tackling violence against women and girls and on ending FGM at home and abroad.
I have always had a very constructive relationship with Theresa May and I look forward to working with her again.
Lynne Featherstone is to replace Norman Baker as Liberal Democrat minister at the Home Office, Nick Clegg has announced.
The MP for Hornsey and Wood Green was appointed Home Office junior minister for equality in 2012. Two years later she became junior minister for international development.
She has also been Lib Dem spokesman for youth equality and was one of the first politicians to push the same-sex marriage bill through parliament.
Liberal Democrat MP Norman Baker, who has resigned as Home Office minister, says dealing with Home Secretary Theresa May was a "constant battle" and relations in the department were "disappointing".
Mr Baker denied claims that he thought he was the same ministerial rank as Mrs May but accused her of treating the department as if it was part of a Conservative government and not a coalition.
He added that he needed a break from ministerial office to spend more time with his family and on outside interests.
Former Tory minister Damien Green has described Norman Baker as a "natural lone wolf, not a natural team player".
He said Baker did not like the fact he had to work under Home Secretary Theresa May and wanted to clear everything himself.
"I think he maybe he had unrealistic expectations of what his job was", Green added.
One of the reasons Lib Dem Home Secretary Norman Baker stepped down is to concentrate on his passion for music.
The former minister is in a band called The Reform Club, for which he is "lead singer and lyricist", and even released a pop single Piccadilly Circus last year.
In his resignation letter to Lib Dem leader Nick Clegg, Baker said his time as minister had "squeezed the time available for my family and outside interests, including my music".
He will still continue in his role as MP for Lewes.
Here is the video for The Reform Club's single Piccadilly Circus:
Former Tory former Damian Green has accused Norman Baker of trying to act as if he had the same ministerial rank as Home Secretary Theresa May.
The ex-Home Office minister told BBC's Radio 4 Today programme: "Norman's problem was he came in ... he gave an interview to his local paper saying 'I'm the Lib Dem home secretary'.
"He regarded himself as being on a par with the Home Secretary and asked for papers from other ministers, he wanted to check what everyone else was doing.
"The world doesn't work like that. If you are a minister of state, in the end you work for the Secretary of State in that department."
Nick Clegg has said he will announce Norman Baker's replacement shortly after calling him an "outstanding" minister.
Labour have claimed the resignation of Norman Baker shows Theresa May is "losing control" of the Home Office.
Shadow Home Office minister Diana Johnson said:
More chaos at the Home Office. Alongside the immigration shambles, the failed experiment of Police and Crime Commissioners and the failure to undertake basic checks into chairs of the child abuse inquiry, it's clear Theresa May is losing control of her Department.
Nick Clegg has written to Norman Baker thanking him for his "brilliant" service as a minister, in spite of well-documented difficulties with his Tory coalition colleagues.
The Deputy Prime Minister wrote:
Thank you for the brilliant job you have done as a Minister over the past four and a half years, first at the Department of Transport and more recently at the Home Office.
However complex the issues have been, or challenging the coalition relations have proved to be, you have handled the political relationships within Government with great skill, always focusing on how to achieve liberal reform wherever you can.
