New N.I minister possibly.
Brandon Lewis is currently security minister. But Tory sources were hinting earlier this week that he would be penalised because of his decision, when he was Conservative chairman, to hold an investigation into Johnson's comment about women in Islamic dress looking like "letterboxes" (an inquiry that saw him subsequently cleared of being Islamophobic). It has also been claimed that he fell out with Carrie Symonds, the PM's partner, when he was chairman and she was head of the press office at CCHQ.
It is not unusual for prime minister's to treat the Northern Ireland Office as a ministerial version of the doghouse - somewhere to send people deemed out of favour. But, for obvious reasons, treating the post in this manner infuriates politicians from all parties at Stormont.
lol, what a cunt, i'm not sure if i believe the reason, though it's hard when it's Boris.
