Later in the week, Audrey throws another spanner in the works in the hope of stopping Gail from leaving for France with Jesse. She warns that Jesse and David are both lying to Gail, but will it be enough to stop the wedding?

2. Gail gets a surprise visitor

3. Gail’s last day in Weatherfield arrives

On Christmas Day, Gail faces a life-changing decision as the day of her wedding to Jesse has finally arrived.

Will she go ahead and leave Weatherfield as a married woman, or will she end things with Jesse and head off on her own?

4. Toyah is arrested

Nick returns from holiday and Leanne quickly puts the next stage of her plan into action, warning him that there’s a problem with the Bistro business accounts. Finding a series of unexplained payments to ‘TLH Holdings’, Nick asks the bank to freeze the account.

Later, police arrive at the Bistro to arrest Toyah on suspicion of fraud.

5. Leanne tries to implicate Nick

Leanne’s anger grows when she finds that Nick has splashed out on Christmas presents for Toyah.

Using this situation to her advantage, Leanne heads to the police station and shows the presents to Craig. She suggests that Toyah and Nick must have been in on the alleged fraud plan together.

6. Toyah and Leanne’s tensions boil over

On Christmas Day, Toyah tries to forget about her arrest ordeal as she helps Nick to prepare the Bistro for Gail and Jesse’s wedding. However, the police soon reappear to announce that Toyah and Nick need to answer further questions about the fraud allegation.

As Toyah grows increasingly suspicious that Leanne is the source of her misery, she confronts her sister and the situation escalates into a full-blown fight.

7. Nick tries to clear his name

Nick seeks legal advice from Adam and Alya after being set up by Leanne. He then tries to do some digging for evidence which proves Leanne’s guilt.

Nick’s unease grows when Amy claims that he sent flirty texts while he was on holiday in Tenerife. As Nick looks through CCTV footage at the Bistro, he spots that Leanne has two phones and could have been responsible for this too.

Meanwhile, Toyah tries a softer approach with Leanne, insisting that she and Nick never meant to hurt her. Will Leanne show any remorse for her vengeful actions?

8. David’s suspicions grow

Debbie invites Shona to attend her New Year’s Eve party at the Chariot Square Hotel. Shona doesn’t seem interested, but Debbie points out that she seemed to be enjoying the hotel well enough when she visited a few nights ago.

David overhears the end of this conversation and his suspicions grow over Shona having an affair.

9. Adam takes a tumble

On Christmas Day, David is confused when Shona doesn’t give him the new aftershave that he’d found hidden away in her bag. When Adam later appears, revealing that he was given aftershave by someone as a Christmas gift, David thinks it’s the final proof that he’s sleeping with Shona.

David asks Adam to join him for a birthday drink, but as his oblivious target downs some whisky, David secretly sticks to water. Before long, David accuses Adam of having an affair with Shona.

Shona and Sarah witness the altercation coming to a dramatic end as Adam falls down a set of stairs.

10. Daniel proposes to Bethany

Bethany gives Daniel an expensive watch for his Christmas gift, but she’s underwhelmed by his reaction.

Daniel is put on the spot when Bethany suggests that it’s obvious he doesn’t want to be with her anymore. He insists that she’s wrong and gets down on one knee to propose. Will Bethany say yes?

11. Bethany reaches a turning point

Bethany thanks Daisy for looking after her clothes at The Rovers.

She confirms that she now wants her old wardrobe back, as she’s feeling confident for the first time since her botched surgery ordeal.

12. Dee-Dee attends an important meeting

Dee-Dee agrees to attend an appointment with a genetic counsellor, who explains the necessary tests to find out whether her unborn baby would be a suitable donor for Frankie.

While Dee-Dee focuses on this, she asks Alya to keep her posted on Lauren’s plea hearing.

13. Lauren faces a big decision over her plea

Lauren talks through her options with her solicitor, who points out that a not-guilty plea would lead to Joel’s murder case going to trial. This would mean Lauren’s unsavoury past being exposed in court, including her connections to the far-right gang.

Max puts forward an alternate argument, suggesting that pleading guilty for a lesser sentence would mean Frankie growing up thinking that she was the villain in his dad’s death. What will Lauren decide to do?

14. Lisa disapproves of Mason

Lisa is concerned to spot a picture on social media which shows Mason in Betsy’s room.

She expresses her worry, but Betsy later finds a way to turn the tables at the factory. When Carla and Lisa publicly announce their relationship to the Underworld staff, Betsy ruins the moment with a sarcastic remark.

Carla tries to stay on good terms with Betsy and suggests the teen should join her and Lisa for dinner at the Bistro. Continuing to keep Lisa and Carla on their toes, Betsy turns up with Mason as her unexpected guest.

15. Ken and Cassie exchange gifts

Ken is delighted when Cassie gives him a thoughtful Christmas present – an album by his favourite composer.
