Westminster Hall, UK Parliament is hosting the Museum of the Prime Minister’s temporary exhibition celebrating 300 years of Parliament and the office of Prime Minister.
The exhibition opened to the public on 16 May 2025 and runs until 12 November 2025.
It offers visitors a glimpse into the rich history of Britain’s highest political office, exploring the constitutional reforms, the crises, the personalities and the parliamentary debates that have shaped our history.
The exhibition consists of a series panels covering the rise to prominence of Sir Robert Walpole, who is widely regarded as Britain’s first Prime Minister, the establishment of the office of Prime Minister and historical information on a selection of former Prime Ministers.
It also charts one of the great parliamentary rivalries, between the Conservative Benjamin Disraeli and the Liberal William Gladstone who clashed in Parliament across 20 years.
One panel includes an image of 10 Downing Street’s famous black door, providing photo opportunities for visitors who will also be able to access a digital guide on Bloomberg Connects accessed by a QR code.
This standalone exhibition in Westminster Hall is separate from the Museum of the Prime Minister ’s wider aspiration to open a temporary exhibition space in central London and establish a permanent museum to explore the achievements, failures and decisions of British prime ministers – a museum about our past to educate our future.
Update: Please note that this well-received exhibition has now ended. It will subsequently tour other venues across the UK – details to be confirmed.
