The leader of Harrow Council has called on the Prime Minister to clear up the Windrush scandal as Commonwealth leaders gathered in London.

Theresa May has come under fire after a number of West Indian migrants who arrived in the UK in the 1940s and 50s highlighted the discrimination they have faced at the hands of the Conservative Government.

Despite living and working in the country for decades, many were refused access to vital medical treatment, lost their jobs or were threatened with deportation.

Cllr Sachin Shah said the Commonwealth summit, involving leaders of all 53 Commonwealth nations, presented the perfect opportunity for the Prime Minister and the Home Secretary to right their wrongs.

And he cited Harrow’s own diverse make up – a 2011 census showed that almost 70 per cent of people were from minority ethnic backgrounds – as an example of what makes the UK great.

He said: “I welcome the Commonwealth summit and hope that it will build on the great relations that our countries have.

“Harrow is one of the most diverse boroughs in the United Kingdom, home to many residents from the Commonwealth, such as Indians and Sri Lankans.

“As it has been covered in the news recently, many of those from that have arrived on the Windrush and their families have been treated in an inhumane and cruel manner.

“The Prime Minister must act immediately to restore justice for all of them.”

Mrs May said earlier this week that she was “genuinely sorry for any anxiety that had been caused”.

She apologised to Caribbean leaders and acknowledged that errors had been made during her stint as Home Secretary.

“I want to reassure you that I take this issue very seriously I will be ensuring the Home Office is dealing with this as well and efficiently and swiftly as they can and giving people every support that we can give them,” she said.

“We welcome them and value them and the enormous contribution they have made to this country.”

Despite this, several of the Windrush generation and their descendants have come forward with further examples of situations where they have been asked to prove their ‘Britishness’.
