Tell 用法請教?

"tell" is a ditransitive verb, that is, taking two objects (indirect object and direct object).
Example:
1. tell + somebody (IO) + something (DO) - He told me a sad story.
2. tell + somebody (IO) + speech (DO) - He told the committee, "I think we should stop the debate now."

Your sentence:
Labour MP Justin Madders told a nearly vacant chamber, between drips, “I think there's ..."
IO = a nearly vacant chamber 一個幾乎完全缺席的議事廳 (沒有省略)
DO = “I think there's ..."
Labour MP Justin Madders 向一個幾乎完全缺席的議事廳發言說：「........」。

'between drips" 這個介詞短語是副詞性質，它修改“told”來表示發言的時間性。亦可放在句子前面，大致意思是說 "在議會停顿之間" 。 (屋頂有裂縫就會有滴水, 因為漏水議會就要暫停。)
