A Tory MP has been accused of Islamophobia over a now-deleted tweet he posted about Sadiq Khan.
Michael Fabricant posted a cartoon showing the Mayor of London's head on an inflatable balloon, engaged in a sex act with a pig.
Mr Fabricant has apologised, saying he "stupidly tweeted it in a meeting without checking it properly".
Sadiq Khan is a Muslim, and eating pork is a sin in Islam. Pork has previously been used in Islamophobic attacks.

Lichfield MP Mr Fabricant said: "Because I was distracted in a meeting and saw it on a tiny iPhone screen, I didn't spot what it really was.
"I would never deliberately put up a racist or Islamophobic tweet to offend people."
Former Conservative Party chairman Baroness Sayeeda Warsi responded, describing Islamophobia in the Tory party as "widespread".
And on and on it goes 🤦🏽♀️— Sayeeda Warsi (@SayeedaWarsi) July 12, 2018
There will be an inquiry- it’s only a question of time.
The problem in my party is too widespread for there not to be.
The question is how much damage we will do to our reputation in the meantime as we drag our feet @Conservatives https://t.co/NYTz0dwIzX
She recently called for an inquiry into Islamophobia in the Conservative Party.
Following Mr Fabricant's tweet, Baroness Warsi said that inquiry was "only a question of time".
She was the UK's first female Muslim cabinet minister.
Some Labour MPs called for Mr Fabricant's suspension.
This is abhorrent. Tory members, the former chair of the party @SayeedaWarsi , and the @MuslimCouncil have all called for an inquiry into Islamaphobia. If @BrandonLewis respect pledge means anything, Michael Fabricant must be suspended immediately. https://t.co/x0fxwnfH3g— Afzal Khan MP (@Afzal4Gorton) July 12, 2018
Can’t believe @Mike_Fabricant tweeted that vile, islamophobic image of @SadiqKhan - thought it was a spoof. He has just deleted it. Describes himself as an “MP dude” in his twitter profile but is clearly an “MP idiot”. @SayeedaWarsi is right on this - her party has a problem.— Chuka Umunna (@ChukaUmunna) July 12, 2018
The 68-year-old has caused anger with his tweets previously, and had to apologise in one instance after saying he would punch a female journalist "in the throat" if he was ever on a talk show with her.
You might also recognise him from an appearance on Channel 4's Celebrity First Dates.
The balloon in the cartoon he posted references the giant blimp being flown over London in protest of Donald Trump's visit to the UK.
Mr Trump has been a regular critic of London's Labour mayor, most recently in an interview with The Sun.
The president said Mr Khan had done "a terrible job" in response to last year's terror attacks in the capital.
The Mayor of London was the person who gave permission for the giant blimp of Donald Trump to fly during his visit to the UK.
He's previously accused Mr Trump of holding "ignorant" views of Islam.
Labour MP Wes Streeting said he'd raised the tweet with the Conservatives, adding: "I'm sick of the mayor's religion being used as a punchline and punchbag by racists and bigots. MPs should know better."
