McCullum Faces Sacking Threat as ECB Prepares 'Ultimatum' After Ashes Debacle

• England coach Brendon McCullum faces potential sacking by the ECB following England's likely 1-4 Ashes series defeat in Australia.
• Despite a Test win, England had already surrendered the Ashes by losing the first three Tests rapidly, mirroring a 1-4 loss in India.
• The ECB is reportedly preparing an 'ultimatum' for McCullum, demanding 'major changes' to the team's environment and culture.
• McCullum's response to this ultimatum will determine his future, with an announcement expected after the T20 World Cup.
• While captain Ben Stokes and Director Rob Key are also under pressure, Stokes' position is considered safer and his feedback crucial.
