January 3rd- Bobs your Uncle

The phrase "Bob's your Uncle" came into being in the 1890s. A politician named Arthur Balfour was chosen as Secretary of State for Ireland. Although he was qualified to undertake this post, his selection was a surprise. It became known that Arthur was the nephew of the Prime Minister, Robert Gascoyne- Cecil (Lord Salisbury.) and people began to say, with a wink, with Robert as your uncle anything is possible! And so it proved for Albert Balfour, who later became Prime Minister himself.
