Outgoing Leaderdale and Melrose Councillor Nicholas Watson says the result in the by-election shows that voters are looking for more local representation, after his party colleague Iain Gillespie won his seat.
Mr Watson has moved to Cumbria to continue working as a clock maker and farmer.
"It is gratifying to know that the Borders Party isn't just about me and my colleague Sandy Aitchison, it is also about an idea whose time has come, people are fed up with national politics in local government and people really want to put in local government, they really want to revive independent politics."
