The Labor Party has launched new attempts to discredit the government of Teresa Mae, and opposition party foreign policy spokeswoman Emily Thornberry said yesterday that there may be a time when the party must call for another vote of no confidence.

The May government survived a vote of no confidence in January, the day after it rejected its agreement to leave the EU for the first time, and the British parliament rejected the deal twice thereafter.

The Sunday Times reports that Mai faces the danger of the resignation of senior ministers of supporters and opponents of exit from the European Union, on the path to be taken in the coming days.

At least six pro-EU ministers will quit if they go out of the EU without an agreement, while pro-exit ministers will resign if they support a customs union with the EU or seek to delay the exit.

The former British minister, Alistair Burt, said Mai was under tremendous pressure from some of her cabinet's top ministers who wanted to leave the EU without an agreement.

Burt quit as secretary of state at the State Department last week to back the vote in parliament and said he did not believe national elections would be beneficial to the country.
