 The Conservative-Liberal Democrat coalition government of 2010–2015 had proposed introducing a more American style system where senior civil servants, such as permanent secretaries, became political appointees.However, this was dropped after it was considered that the existing permanent civil service style was better-suited to the government of the United Kingdom.The political neutrality of the civil service was called into question during the 2016 - 2019 Brexit negotiations, with political figures such as Brexit Party Leader Nigel Farage accusing the civil service of having a "pro-Remain bias".
