However, the people featured in this series have taken saving to a whole new level. In the second edition, he introduces us to a woman who went from big debts to owning her own home – by living in her sister’s garage for two years. Plus, there’s a family who are saving hundreds by foraging for their food.

The Psychedelic Drug Trial (BBC2, regions vary)

Mental health issues seem to constantly be in the headlines these days, with an increasing number of people opening up about their problems, particularly their battles with depression. This fascinating documentary, filmed over the course of 16 months, follows a groundbreaking new trial at Imperial College London in which, under controlled conditions, a psychedelic drug is being tested for its effectiveness in combating the problem alongside that of a standard antidepressant. Professor David Nutt, Dr Robin Earhart-Harris and Dr Rosalind Watts lead the experiment, in which they examine the immediate and long-term effects on the participants while hoping to discover a revolutionary method of treating one of today’s biggest medical challenges.

Prince Harry and Meghan Duchess of Sussex, holding their son Archie Harrison Mountbatten-Windsor

A Very Royal Baby: From Cradle to Crown (C4, 9pm)

Royal babies are always a cause for celebration – it’s almost as if they become the nation’s offspring. But down the centuries, the way in which their arrival has been announced has changed out of all recognition. This new one-off documentary tackles the subject, but with a particular focus on the last 100 years, which would cover the births of the Queen, all four of her children and eight grandchildren, including Prince Harry. Much of the focus of the programme is on his offspring and the media intrusion he and his wife Meghan feel they have suffered – giving insights into what happened during her baby shower probably won’t ease their relationship with the press either. But there’s also an explanation of why the royals have swapped the tradition of giving birth at home in favour of private hospitals.

However, judges Patrick Grant and Esme Young will be giving the sixth sewer their marching orders tonight. But first there are three challenges to face during reduce, reuse and recycle week. The haberdashery’s fabric stash has been replaced by charity shop clothes and soft furnishings from which the competitors must make a waistcoat, a stylish women’s garment and a dress utilising old jeans.

Bijan Ebrahimi: a police force and council "repeatedly sided with the abusers" of Bijan, who was murdered after being wrongly accused of being paedophile, a report has found

Murdered by a Mob (C5, 9pm)

In 2013, disabled Iranian refugee Bijan Ebrahimi was murdered by a neighbour. It was the culmination of seven years of harassment and terror for the 44-year-old, who had reported numerous death threats made against him. His tormentors falsely accused him of being a paedophile, and his tragic death gained international media attention amid claims of institutional racism. This documentary uses CCTV footage and expert testimony to piece together what happened in the days leading up to that fateful night.

Johnny and Bev.

Johnny Vegas: Carry on Glamping (C4, 10pm)

It’s week three of the comedian’s efforts to create the ultimate glamping site, and it still feels as if he’s a million miles away from having everything finished. Luckily for him, his assistant Bev is a no-nonsense sort of person and is determined to get their field in Yorkshire ready for guests as soon as possible. Johnny’s decision to make extravagant last-minute changes to the Maltese bus design doesn’t help matters, but a converted American school bus and a Morris Minor Caravanette soon put a smile on his face.
