Morning all

We might go back to the phils over xmas (depending on outragous flight costs of course) but I've just seen that my wifes passport expires in april next year. Will this be a problem for coming back into the UK with less than 6 months remaining on her passport. Don't want to go through all that to get her turned away at birmingham immigration! Oh yes she has a ILR visa. Is there a maximum time before passport expiry that we can apply for a new one at the phils embassy in london?
