Cabinet minister Oliver Dowden, a key ally of Prime Minister Rishi Sunak, said Sir Gavin sent texts to Ms Morton "in the heat of the moment at a very difficult time".Oliver Dowden, Rishi Sunak's right-hand man, told us his texts weren't acceptable, but tried to defend him by saying they'd been sent at a difficult moment in Parliament.And while he hadn't seen the texts, Mr Sunak had been warned there was a bullying complaint about Mr Williamson and decided to give him a job anyway, while promising his government would be all about integrity and professionalism.Labour deputy leader Angela Rayner said Mr Sunak's decision to bring Sir Gavin back into government saw him put "party management before the country" and his judgement was "in question".Liberal Democrat Deputy Leader Daisy Cooper MP said: "These shocking revelations raise yet more serious questions about Rishi Sunak's judgement..."If the prime minister was serious about restoring integrity, he would sack Gavin Williamson.""
