Robert Howard Marris (born 8 April 1955[1]) is a British Labour Party politician, who served as the Member of Parliament (MP) for Wolverhampton South West.

He served his articles of clerkship in Wolverhampton and went to work for Thompsons Solicitors, the trade union law firm,[3] until he was elected to the House of Commons.

In the run-up to the 2015 election, both Marris, his main opponent, Paul Uppal and even UKIP agreed that immigration was no longer a key issue.

[8] Marris expressed concern about zero hour contracts, foodbanks and workers earnings below living wages and whilst Uppal highlighted the improvement in community relations.

[9] The bill was praised by Philip Collins, a leader writer for The Times as "a sophisticated and humane attempt" to clarify the law before the courts do so and which unlike religion "will actually ease suffering."

During the 2020 Labour Party leadership election, a video emerged of candidate Rebecca Long-Bailey, who at the time of the ultimately unsuccessful 2016 leadership challenge had been in post as Shadow Chief Secretary to the Treasury for 3 days, accusing Marris of having his assistant delete shared Shadow Cabinet files after resigning in an attempt to undermine loyalist frontbenchers.

[15] Marris strongly denied there was any malicious intent and said that his assistant deleted the files because the document was created by his Parliamentary office and was not the property of the Labour Party.
