David Cameron today joined Prime Minister Theresa May in campaigning for the Conservatives in Witney after his resignation from the seat triggered a by-election.
Former PM Mr Cameron resigned as an MP last month saying he did not want to be a "distraction" for the new Prime Minister.
Today he gave his support to the Conservative candidate for the constituency Robert Courts ahead of the by-election on Thursday.
Mr Cameron, 49, has represented Witney since 2001, becoming Conservative leader in 2005 and PM in 2010.
Labour leader Jeremy Corbyn also visited the constituency to lend his support to Labour candidate Duncan Enright.
Also in the running for the seat is Larry Sanders for the Green Party, businesswoman Liz Leffman for the Lib Dems and Dickie Bird for Ukip.
