This week on Westminster Insider, host Sascha O'Sullivan lifts on the curtain on the best political lunches — who to invite, where to go, and what to talk about.

She speaks to Vivek Singh, owner of the Cinnamon Club, a SW1 culinary institution, about the two decades of drama and intrigue he's witnessed over his famous lamb shanks. Singh tells Sascha about the best tables — where you can see everyone but no one can see you — and how Gordon Brown was partial to a spot of grouse.

Former Labour MP and member of Tony Blair's government Siôn Simon explains why the classic lobby lunch between journalists and politicians is actually "underlyingly stressful" and Sun on Sunday Political Editor Kate Ferguson tells Sascha how to warm up an MP to get them to spill the beans.

Sascha speaks with Freddie Sayers, CEO of Unherd, which owns the Old Queen Street Cafe — a new favorite haunt of politicos of all stripes. Former political correspondent turned restaurant critic Charlotte Ivers tells Sascha why politicians have terrible taste in food.

And the FT's Henry Mance recalls settling in for a port or three after lunch with Nigel Farage.
