Seems they broke an agreement with GG and released said clip before polling day. Clear motive to undercut WPB's electoral successes then. Brief response on Galloway's nitter:

This is a calculated move. Galloway chose Novara to deliver this message because he wants a security lock against left joining WPB - he needs clarity on his strategy, which is to find the populist "diagonal" between left and right and build an oppositional movement on that line.

NEW: in an interview with @novaramedia, George Galloway repeatedly says that gay relationships aren't "normal", and children shouldn't be taught to think that they are.
Full interview out on Sunday at 3pm.]

Maybe, but I'd veer more towards that calculation coming from Novara. Making out they're shocked when none of this is a secret, on the eve of local elections? Highly suss.
You know what happened to him, right?

George Galloway MP @georgegalloway
And in breach of the agreement that it would be released on Sunday not on eve of poll. Bastani and Novara Media are bad faith actors
