Clydebank’s MP has paid tribute to his late brother Graham while criticising the Prime Minister over the views of one of his advisers.

During Prime Minister’s Questions, Martin Docherty-Hughes asked Boris Johnson why Andrew Sabinsky was employed despite discriminatory comments on eugenics – the widely-discredited science of controlling evolution by excluding people judged “inferior”.

The local MP told the House of Commons how his late brother Graham died aged 15 from cerebral palsy.

He was unable to walk, talk or feed himself, but Mr Docherty-Hughes told his colleagues in the Commons how he brought love and joy to all who knew him.

He asked the Prime Minister “to advise the House, on behalf of every disabled person on this island, why Andrew Sabinsky was put at the heart of his government and was not removed from his position immediately, when his abhorrent views became apparent?”

The former Downing Street adviser, who later resigned, believed forced long-term contraception would rid the country of its “permanent underclass”.

In response, Mr Johnson said: “I certainly don’t share those views and neither does anyone else in this government. And that individual no longer works for this government.”
