The Covid-19 pandemic has led to a government inquiry into the UK's response to the crisis, and there is a dispute between the inquiry and the government over access to information.
The inquiry's chair, Heather Hallett, has asked for access to the unredacted WhatsApp messages of former Prime Minister
Boris Johnson and his staff.
The government has argued that the inquiry does not have the power to request personal messages that are not related to work.
However, some members of the government, including Defense Committee Chair Tobias Ellwood, have called for the government to hand over the messages.
The decision over whether to comply with the inquiry's request is expected to be made on Thursday.
