Sky News is planning its own leaders’ event in the key battleground seat of Grimsby and Cleethorpes, where we have been regularly reporting on the issues facing local residents.
Voters will be given the opportunity to put questions directly to the leaders.
Labour leader Sir Keir has agreed to attend, while negotiations are ongoing with Mr Sunak’s team.

Labour extends lead over tories in exclusive poll for Sky News
Since then, they have been a key part of general election campaigns, with Theresa May in 2017 being the only leader refusing to take part since 2010 – a decision she later told Sky News she regretted.
The decision to hold the debate in Grimsby comes after the seat turned Conservative in 2019 for the first time since the end of the Second World War.
Many people at the time felt a cultural rift with the Labour Party.
Grimsby has now been combined with Cleethorpes, where the Tories have been in power since 2010, but support is fading.
Cleethorpes has been a bellwether seat since its formation in 1997, backing the largest party in Westminster in all seven elections since then.
The constituency contains a rural conservative base, as well as urban voters, who in more recent years backed the promises of levelling up and Brexit offered by the Conservatives.
The complex composition of this new constituency means it is shaping up to be a key battleground.
