Theresa May is facing a second reshuffle of her Cabinet in a week following the resignation of Priti Patel.
The former International Development Secretary quit her position amid a firestorm over secret meetings she held with Israeli politicians.
While on holiday in Israel, she met a number of politicians – including Prime Minister Benjamin Netanyahu – and held two more meetings with senior Israeli figures in London following her return without clearing them through official channels.
Patel resigned after being summoned back from a tour of Africa, acknowledging her conduct had fallen below the standards expected from Cabinet ministers.
The prime minister is now dealing with the prospect of replacing her, which is politically sensitive.
May might attempt to replace her with another MP who backs Brexit – like Patel – in order to placate any rebellion from Eurosceptic MPs on the backbenches.
Time is against the prime minister as Brexit talks are due to resume again in Brussels amid her current domestic difficulties.
