Prince Andrew has reportedly been making secret nightly visits to Windsor Castle to see the Queen.The Duke, who turned 62 on Saturday, was allegedly driven to see his mother every day last week after a settlement was reached in his sexual assault case against Virginia Giuffre, thought to be worth £12 million. The father-of-two reached a settlement, which he will reportedly receive help from the Queen to pay, with the claimant out of court, which means he will no longer be required to appear in a US court for a jury trial.
