" Hollyoaks bosses have today released a new promotional shot for Mercedes and Riley&amp;#039;s forthcoming wedding, which arrives on screen later this month. Mercedes (Jennifer Metcalfe) has a turbulent time ahead in the build-up to the ceremony as scheming couple Warren (Jamie Lomas) and Mitzeee (Rachel Shenton) start blackmailing her and Carl over their affair, threatening to reveal all on the big day unless they hand over \u00A350,000. Riley&amp;#039;s brother Seth (Miles Higson) and Mercedes&amp;#039;s sister Jacqui (Claire Cooper) are also aware of the pair&amp;#039;s secret and may have their own reasons for wanting the truth to come out over Carl&amp;#039;s betrayal of his son. Doug (PJ Brennan) is also keen to reveal all to Riley (Rob Norbury) in a bid to put a stop to Warren&amp;#039;s vengeful blackmail, but with the village bad boy threatening him, he faces a difficult decision over what to do next.  From left to right: Jacqui (Claire Cooper), Seth (Miles Higson), Carl (Paul Opacic), Riley (Rob Norbury), Mercedes (Jennifer Metcalfe), Warren (Jamie Lomas), Mitzeee (Rachel Shenton), Doug (PJ Brennan). With so many guests knowing Mercedes and Carl&amp;#039;s dirty secret, the atmosphere will be tense as their affair storyline reaches its climax.  Will Carl (Paul Opacic) find the guilt too much and spill the beans? Could Mitzeee and Warren get their revenge and publicly destroy the Costello clan? Might Seth, Doug or Jacqui reveal the truth? Or will Mercedes and Riley defy the odds and actually get a happy ending? Hollyoaks airs the compelling build-up to the ceremony in next week&amp;#039;s episodes, while the ceremony itself airs on Monday, October 17 at 6.30pm on Channel 4. In the meantime, fans of the soap are currently discussing the upcoming event on Twitter with the hashtag #WAGWedding.  &amp;amp;gt; Hollyoaks&amp;#039; Rachel Shenton teases Mitzeee, Costello revenge plot&amp;amp;gt; Hollyoaks unveils dark Mercedes, Riley wedding trailer&amp;amp;gt; Hollyoaks teases Mercedes, Riley wedding blackmail - video&amp;amp;gt; Read more Hollyoaks spoilers and news "^^<http://www.w3.org/2001/XMLSchema#string>
