Labour in the Synagogue

The Jewish Chronicle reports today that Lawyer Sarah Sackman will be the Labour candidate in the Finchley and Golders Green constituency at the 2015 general election.

Apparently, “Ms Sackman was selected at a party meeting at Finchley Progressive Synagogue on Sunday.”

One may wonder why does the Labour select its candidate in a Synagogue?  Do they also select candidates in churches and mosques?
