Labour MP Rupa Huq has confirmed that her Westminster office has received a suspect package, and is currently cordoned off by police.
A staff member opened a package containing a sticky liquid, and is being taken to hospital.
The package contained what she described as an “Islamophobic” letter.
This follows the receipt of similar packages on Monday by fellow Labour MPs Mohammad Yasin and Rushanara Ali. These were later deemed non-hazardous.
