As announced today, Lady Hale has been appointed the next (and first female) President of the Supreme Court, to replace Lord Neuberger as from 2 October 2017. Lady Hale is currently Deputy President, so that role will have to be filled when her appointment takes effect.
There will also be three new Supreme Court Justices from 2 October: Lady Justice Black, Lord Justice Lloyd Jones and Lord Justice Briggs.
Also from that date, Lord Justice Burnett will become the new Lord Chief Justice, the Head of the Judiciary of England and Wales. His appointment was announced last week.
