After resigning as foreign minister last week over Prime Minister Theresa May's compromise plan for Brexit, Boris Johnson is back at his old job as a columnist at the eurosceptic Daily Telegraph newspaper.

"He's Back," the paper said on its front page on Monday.

Johnson was named foreign minister in July 2016 after playing a leading role in the Brexit referendum campaign.

He was forced to give up his regular columns, which a spokesman said were "inappropriate" for his new role.

When he gave up the newspaper job he also had to renounce the salary of £275,000 that went with it for a more modest ministerial income of £143,789.

The 54-year-old Johnson, who is famous for his frequent gaffes and off-colour quips, started his career as a journalist and has worked on and off for the Daily Telegraph for 20 years.
