Vandals have targeted a Hampshire museum dedicated to commemorating the D-Day landings as it prepared to reopen following a revamp.

The D-Day Museum in Southsea,  has had to cancel its relaunch, which was due to be attended by veterans and local dignitaries, following the break-in during which Poppy Appeal cash was also stolen.

Lee Hunt, Portsmouth City Council Cabinet member for culture and leisure, said: ''We can't quite believe we're having to cancel this morning's grand opening of the D-Day Museum, but a break-in and act of vandalism has forced us to postpone.

''It's horrendous to report but the spectacular, brand new frontage has been smashed, and Poppy Appeal donation money stolen.

''It looks as though something like a breeze block has been thrown at the window to gain access and money from donations stolen.

''This is really upsetting for everyone involved getting the museum ready in time for half-term and for Remembrance Day.

''We're saddened to disappoint our veterans and visitors who were due to attend today.

''But this will not deter us. We'll repair the damage, we'll do everything we can to catch those responsible, and we will have our fantastic opening as soon as possible.''
