A day spent on constituency matters. In the news, the Duke of York's military titles and royal patronages were returned to the Queen. Prince Andrew, 61, would also stop using the style His Royal Highness in an official capacity. It came as he faced a US civil action over sexual assault allegations - claims he has consistently denied. A source close to the duke said he would "continue to defend himself" against the case brought in New York by Virginia Giuffre. A judge in the city ruled on Wednesday that the case brought by Ms Giuffre could continue, after the prince tried to have it dismissed. This is a dark moment for the Prince and I feel desperately sorry for the Queen. Extraordinarily, MI5 issued a rare warning that an alleged Chinese agent had infiltrated Parliament to interfere in UK politics. An alert from the security service said Christine Ching Kui Lee "established links" for the Chinese Communist Party (CCP) with current and aspiring MPs. She then gave donations to politicians, with funding coming from foreign nationals in China and Hong Kong. All this followed a "significant, long-running" investigation by MI5, Whitehall sources told the BBC. One of the MPs funded by Ms Lee was Labour's Barry Gardiner, who received over £420,000 from her in five years - but he said he had always made the security services aware of the donations.
