You don’t get to hide it, the press knows that someone in the area won and they will quickly identify who it was, they’ll then basically give you the offer of doing an interview for a nice fluffy piece, or if you refuse, they’ll dig dirt and publish a nasty one.

This is what happened when my friend’s mum won about 15 years ago anyway. Wasn’t even a “huge” jackpot - just over £1 million - but she didn’t want her friends and neighbours to know ... decision was taken out of her hands. And she did eventually lose some friends and had to move somewhere new. She lived on an ex-council estate but had no intention of moving, but got “othered” as soon as people on the street knew she now had money.
