Theresa May rolled the dice with a dramatic reshuffle of her ministerial team as she battles to cling onto her job and stop her own party from tearing up her Brexit deal.

The prime minister reduced the power of her critics and promoted allies to key positions as she took personal charge of the final days of the U.K.'s divorce talks with the European Union.

The appointments round off an extraordinary week in which seven members of her government quit their posts, and a plot to oust her from power gathered momentum. May's perilous position puts at risk the fruits of two years of British exit negotiations and raises the chance it will crash out of the EU without a deal in March.
