"What is Lineker's defence?
Lineker falls into a slightly different category both because of his contract and his role as a sport presenter.
A BBC spokesperson said: "Gary is not involved in any news or political output for the BBC.
"As such, any expression of his personal political views does not affect the BBC's impartiality."
Lineker only presents sports coverage for the corporation, and is not a journalist or involved in news coverage or commentary.
Previously, the corporation has also defended his right to voice his opinions freely because of his contract.
In 2016, when he was
criticised for some tweets about child migrants, the BBC responded by saying: "Gary is a freelance broadcaster and this is a personal Twitter account."
