Patel, a former international development secretary who has played a key role in Boris Johnson's leadership campaign, takes over from Sajid Javid, who has been appointed chancellor by the new Prime Minister. Priti, an ardent Brexiteer who was among the most vocal critics of Theresa May's Brexit strategy, took charge as Britain's first Indian-origin Home Secretary in the newly-unveiled Boris Johnson Cabinet on Wednesday.
Patel was sacked by Theresa May in 2017 for breaching the ministerial code after holding unauthorised meetings with Israeli politicians.
A long-standing Eurosceptic, Priti Patel had steered the Vote Leave campaign in the lead up to the June 2016 referendum in favour of Britain's exit from the European Union (EU).
The 47-year-old was first elected as a Conservative MP for Witham in Essex in 2010 and gained prominence in the then David Cameron led Tory government as his Indian Diaspora Champion.
She went on to be appointed to junior ministerial posts, Treasury minister in 2014 and then Employment Minister after the 2015 General Election, before Theresa May promoted her to Secretary of State in the Department for International Development (DfID) in 2016 until she was forced to resign the post in 2017.
