Brexit should be delayed if Parliament does not approve a deal in the coming days, three cabinet ministers have warned publicly for the first time.

Ahead of crucial votes in the Commons, Greg Clark, Amber Rudd and David Gauke said time was running out and that they hoped for a breakthrough in negotiations soon. If not, they said they are prepared to defy Theresa May and vote for a delay.

Meanwhile, Labour leader Jeremy Corbyn said if his party won power he would renegotiate a Brexit deal with the European Union and could hold another referendum.

The Serious Fraud Office (SFO) has dropped its investigations into aerospace firm Rolls-Royce and drugs giant GlaxoSmithKline. The SFO said there was “either insufficient evidence” or it was “not in the public interest” to continue.

Rolls Royce was being investigated over concerns about bribery and corruption, which led the firm to enter into a deferred prosecution agreement in 2017. GSK’s probe concerned “commercial practices” at the company.
