Scroll down for video . Attack : Shadow cabinet office minister Chi Onwurah has accused Marks & Spencer and the Natural History Museum of 'gender-specific marketing ’ over range of dinosaur tshirts . But a spokesman for the attraction questioned her agenda , telling the Mail : ‘ In the run up to the election , she has her own motivations ’ . The launch of the clothing range in January sparked a huge row , with critics accusing both the museum and the retailer of sexism . The range of clothes produced by M & S in partnership with the museum – which is famous for its dinosaur exhibition – includes pyjamas and t-shirts with images of dinosaurs on them . Campaigners said it was wrong only to target boys with the clothes and that girls should also be encouraged to take an interest in natural history . Yesterday Miss Onwurah wrote on Twitter : ‘ If you ’ re in London next Monday help tell the dinosaurs in @ NHM_London girls want a share in science too # hearusroar . Miss Onwurah said the t-shirts was excluding girls from science . She also tabled a series of questions in Parliament accusing the museum of ‘ gender specific marketing of toys ’ and failing to ‘ target boys and girls equally ’ . Criticism of the range has been led by the ‘ Let Clothes Be Clothes ’ campaign . When the row first exploded the group ’ s co-founder Ruth Lopardo said : ‘ I was astounded a national museum , which ought to have a clear access-forall policy , should license designs to M & S that are only marketed at boys . ‘ How have these two national institutions , M & S and the Natural History Museum , managed to get through the entire product development cycle , from the initial idea to the product on the shelf , without anyone thinking that perhaps dinosaurs and natural science don ’ t just appeal to boys ? ’ A Marks & Spencer spokesman said : ‘ This is a brand new partnership and , as with any new range , we have listened carefully to feedback from our customers on how they would like to see it evolve . ‘ Our design team is working with the Natural History Museum on expanding the range to include products for girls. ’ A spokesman for the Natural History Museum said : ‘ We are currently working with the Marks and Spencer design team to expand the range to include products for girls . Licensing retail items plays an important role in generating revenue to help fund our work . ‘ The Natural History Museum is passionate about science learning and careers for all . Products in the Museum shop are displayed without gender differentiation for children . ’
