What are the Arguments that support the idea that Backbench MPs are Influential in UK Politics

-Backbenchers have become more Willing to 'Defy the Whip' and vote Against the Government. This helps the House of Commons hold Government to Account. EG 2020 saw 38 Tory MPs vote AGAINST Gov Plans to allow Huawei in UK 5G Network. This led to a U Turn after it had Passed. -The Backbench Business Committee (BBC) gives Backbenchers a Louder Say on Issues debated on in the House of Commons EG: BBC got a Debate about Awareness to Teenage Cancer -Backbenchers has seen Increased Influence when Parliament is Hung - Ability to Call Government into Question is Increased. EG 2017-2019 saw no Majority which meant the Speaker had allowed more Urgent Questions giving Backbench MPs the ability to Summon Ministers to be held to Account (Brexit, Grenfall Tower, Universal Credit)
