Tim Farron will debate will debate national park elections in parliament, in a bid to give locals more of a say on how they're run.
It comes as part of his campaign to bring about direct elections to the boards of National Park authorities across the UK.
He recently approached Deputy Prime Minister Nick Clegg on the subject during Parliamentary questions.
He highlighted the importance of national park boards containing elected representatives in order to ensure they are accountable for the decisions they make.
I am delighted to have secured this debate, and we can now take a step towards giving local people a formal say over the management of national parks.
"I hope the minister will agree that the huge significance of the national park to the lives and communities of people in South Lakes means they deserve a say in how it's run.
"It will be a fantastic chance to raise my concerns about the recent controversies over the plans for Brockhole, and these will provide an important reference point in the debate as I seek to ensure local people's voices are heard when it comes to the national park."
