The MP for Totnes MP said he would not have taken the same "course of action" as Dominic Cummings, following his decision to drive 260 miles with his wife and child during the Covid-19 lockdown.
Conservative backbencher Anthony Mangnall (pictured) revealed on Facebook he was not surprised at the "extreme anger and dissatisfaction" with the prime minister's senior adviser.
Mr Mangnall praised the "extraordinary sacrifices over the last two months" made by his constituents and people around the country.
He added: "I have not seen my mother, father or brothers or recently arrived nephew.
"So, to see that others have chosen to follow the rules differently is incredibly difficult."
Mr Mangnall acknowledged he could not "pretend to know the course of action a father might take" to keep his child safe, but said he shared "many of the concerns that have been raised" with Mr Cummings actions.
Spending time defending an adviser is not a good use of time, especially given the many fears and concerns about people's future and their livelihoods."
