Grant boost for convoy ship HQS Wellington

Convoy ships which escorted vital supply vessels across the Atlantic and fought off German U-boats were crucial in helping Britain win WWII.
Now, there is only one left afloat - HQS Wellington (formerly HMS Wellington) - and it has been on the River Thames next to Temple Tube station since 1948.
With the help of a heritage grant, members of the public will have the chance to climb aboard and explore what is frequently described as one of London's ''hidden gems''.
