Robert said: "Social enterprises make a positive difference in communities up and down the country - and nowhere more so than West Oxfordshire. They are set up to trade for a social purpose, and use business to improve the world around them.
"Saturday marked this year's Social Saturday event, which is all about championing these important businesses.
"I was pleased to take the time to support the fantastic West Oxfordshire social enterprise that is Yellow Submarine, and it was great to see so many local residents doing the same - whilst of course enjoying their wonderful free cakes!"
