Today, I received some promotional material from the Big Lottery Fund. They are offering grants to World Way II veterans to visit the places where they sat action or to attend a commemorative event in the UK. Widows and widowers can also apply. You need to travel by the end of the year and you can get a grant even if you've already paid for your trip.
If you know a veteran who might be interested, you can get more information here or by calling 0845 0000 121.
