Former Green Party politician Larry Sanders has cast his vote for his brother Bernie Sanders, the US presidential hopeful taking on Hillary Clinton.

Mr Sanders, from East Oxford is a former social worker, legal adviser and activist who only recently stepped back from frontline county council politics with the Green Party.

Now the 80-year-old is trying to do his bit for the campaign of his brother, Vermont Senator Bernie Sanders.

He is promoting ‘Oxford for Bernie’, one of five campaigns set up in the UK to encourage Americans living abroad to back Sanders-the-younger, who is reported to be taking the youth vote by storm with his signature firebrand style and socialist views.

He cast his vote at the Rothermere American Institute in Oxford in the Democrats Abroad Global Presidential Primary.

Larry Sanders said earlier: "Coming out of the Iowa race, Bernard now has the support to go all the way. What he has done is amazing.

"Even if he weren’t my brother, I would still admire him as a great man.

"But as his brother, I am also very proud."

Bernie, 74, has fought Mrs Clinton to the wire and the American media says his strong campaigning has left the Clinton team shaken and opened up the Democratic race, after the former Secretary of State’s comfortable lead in the polls evaporated at the ballot box.
