Hucknall MP tweets he's 100 per cent behind Boris Johnson

At Prime Minister’s Questions in Parliament, Mr Johnson apologised for what had happened and said he understood why millions of people in the country who were locked down at the time would be so angry about it.

Several opposition MPs and a number of Tory backbenchers have called for Mr Johnson to resign.

But several senior cabinet colleagues have rallied around Mr Johnson and now Mr Spencer, the Government’s chief whip, has added his voice of support.

He tweeted: “PM continually delivers for the country.

“Got Brexit done, world-beating vaccine roll-out, 400,000 more jobs than pre-Covid, keeping schools open & children learning, building back better for all.

"All thanks to the leadership of @BorisJohnson – 100% behind him.”
