The former Prime Minister will appear in tonight's episode, along with a host of politicians, actors and musicians as the The Last Leg pays tribute to murdered MP Jo Cox.

Tony Blair is to make an appearance in a special episode of Channel 4′s The Last Leg marking a year since the death of Labour MP Jo Cox.

The former prime minister will star in a sketch alongside the show’s Adam Hills, Alex Brooker and Josh Widdicombe as part of The Last Leg: Re-United Kingdom.

The three hosts will bump into Blair in a lift, where he interrupts their bickering and demands they set aside their differences to celebrate the life of Ms Cox, who was shot and stabbed on June 16 last year by right-wing extremist Thomas Mair.

The show will pay tribute to the mother of two by reminding viewers of what unites us rather than divides us. Viewers will see former political rivals Tony Blair and William Hague  set aside their differences as well as Alastair Campbell and Ed Miliband.

The two-hour live special comes ahead of The Great Get Together this weekend, where thousands of people will gather for small picnics and community events across the UK, many organised by The Jo Cox Foundation.

Also appearing in tonight’s show are Nick Clegg, comedians Jon Richardson and Stephen Mangan, actors James Buckley, Lily Cole and British band Elbow.

Meanwhile, Ed Balls, former Labour MP, and Michael Gove, newly appointed Environment Secretary, take an awkward ride in a “lift of reconciliation”.

Channel 4 said: “It may only be a short lift ride but perhaps a shared love of Korean pop music and dance will help them settle their differences by the time they reach their destination?”

Can Ed teach Michael the moves to his infamous Gangnam Style routine that dazzled the viewers of Strictly Come Dancing?

The Last Leg: Re-United Kingdom is on tonight, 9pm on Channel 4.
