Chapter 9: From Fragmentation to Unity? Brexit and the Conservative Party Under the Leadership of Boris Johnson

The Europe issue was long a basis of intra-party divisions within the Conservative Party, and the 2016 referendum on the United Kingdom's continued membership of the European Union revealed the extent of the divide. The decision of the UK electorate to leave the EU was expected to resolve the issue and allow for a return to unity within the Conservative Party. Yet, under the leadership of Theresa May, divisions on the Europe issue endured. Boris Johnson succeeded, where his predecessors had failed, in restoring intra-party unity. He successfully secured the backing of party members and the electorate, and the loyalty of the parliamentary party, by strategically prioritising the politics of support and placing Brexit at the core of his statecraft. However, it was also the extent to which Johnson was willing to go so as to silence opponents of his Brexit policy that characterised his leadership.
