Two Goa Congress lawmakers met BJP president Amit Shah in Delhi today and declared that they are switching sides as the ruling party tries to hold its coalition together in the tiny seaside state while Chief Minister Manohar Parrikar battles a pancreatic ailment. Dayanand Sopte and Subhash Shirodkar left for Delhi late on Monday night and, until their meeting with Amit Shah, remained very secretive despite loud speculation about their party swap.
