Equality between wives

Which wife should one take for Hajj first?

Q: A man decided to go for haj with his wife but was not accredited to that year. They both got accreditation the following year, however, during the year he got married to a second wife. What are the correct rulings regarding his haj,  should he now go without his first wife because he can not afford to take both wives and it will take some time for his second wife to be accredited, or should he take the first wife as planned and make up the time with his second wife on return, or is he now indebted to take the second wife for haj also even though he can not afford to. If the husband and wife go for 6 weeks on the haj journey, should he on return spend six weeks with his second wife.

Taking a second wife without informing the first

Q: Is it permissible for a husband to get into a second marriage without informing his first wife? Even after the second marriage he lied to his first wife and didn't let her know two or three years after the second marriage. Now the wife came to know and is in shock since the first marriage was 17 years old and the first wife was also quite young and a mother of four kids. She now wants her husband to divorce the second wife but husband is not willing. The second nikkah was also not announced in both sides.
