A Labour shadow minister has been branded "shameful" for using the Duke of Edinburgh's decision to retire to promote a campaign about pension inequality.

Chi Onwurah was forced to defend her decision to tweet about Prince Philip's announcement after Conservative candidate Nadhim Zahawi called on her to apologise for the remarks.

Ms Onwurah tweeted: "Congratulations to Prince Philip on retiring in financial security at time of his choosing from a job he enjoys #forthemanynotthefew #waspi."
