Reacting to the announcement that Butt would stand, Sharon Osbourne suggested on social media she might stand in the Birmingham elections on 7 May too.
The leader of the city’s Conservatives, Robert Alden, invited her to join them to “help keep extremists out of Birmingham City Council”.
He said his message to Osbourne, if she wanted to join them, was “just give us a call”.
Sureena Brackenridge, the Labour MP for Wolverhampton North East, said: “I am stunned that someone who was found to be a terrorist, who planned to blow up a British consulate, is now putting himself in a position to represent people of Sparkhill.”
Jess Phillips, the Labour MP for Yardley in Birmingham told ITV News: “The idea that people who have been convicted of terror offences underplaying that as having had a colourful past and standing to represent part of my family in that area, I find that absolutely appalling.”
A full list of candidates for the Sparkhill ward will be available on the BBC website once it is finalised.
