"Instead of "in Europe but not run by Europe", we will be out of Europe and yet wholly subject to European rules".
His brother Boris, who quit as foreign secretary in July, praised his decision, saying the brothers were "united in dismay" at the Prime Minister's handling of the negotiations.
In an article sent to journalists, the MP for Orpington said he would vote against the withdrawal agreement which the prime minister was trying to agree with the European Union, describing it as "a awful mistake".
