ROYAL Navy minehunter HMS Ledbury leaves Portsmouth on Tuesday for a four-month deployment in the Mediterranean.
She was due to pass the Round Tower in the afternoon but will now leave at around 10.10am.
The minehunter and her 42 sailors will be taking up the task of defending sea routes in the Med. She will be part of a permanent Nato force which works all year round defending sea routes from mines.
Meanwhile, Portsmouth-based minehunter HMS Cattistock returns to the city from a similar mission on Sunday at 3.30pm.
