British PM Boris Johnson with his brother Jo Johnson

British Prime minister Boris Johnson has been dealt another blow as his brother Jo Johnson announced that he is quitting the UK government.

In a tweet, Jo Johnson said that he has been torn between family and loyalty and the national interest as a whole.

He further said that it is an unresolvable tension and time for others to take on his roles as a Member of Parliament and a minister.
