UK CONTRACT LAW PROBLEM QUESTION

Rebecca has recently retired from a long and wealthy career as an international basketball coach. Rebecca's son, Olamide, always helped managed Rebecca's financial affairs while Rebecca was working abroad. To enjoy her retirement, in September 2021, Rebecca moved to a house in Clacton overlooking the local beach. Olamide, who lives in Edinburgh became upset when he was told about Rebecca's move because this meant that it would be more difficult to communicate with his mother. Rebecca and Olamide began to have regular arguments.

In January 2022, Olamide demanded that Rebecca gift Olamide a small amount of money, and also asked that Rebecca sign a mortgage so that Olamide could buy a house closer to Clacton. Rebecca spent many weeks considering the requests and decided that having her son live closer to her would be advantageous. In February 2022, Rebecca gave a gift of 1,000 to Olamide. Also in February, Rebecca signed an agreement with Bayleaf Bank guaranteeing a 200,000 mortgage taken by Olamide. Rebecca read the agreement in detail. Rebecca also signed a document stating that she fully understood the terms of the agreement. In April 2022, it turned out that Olamide had not made any payments on the mortgage due to losing his job, and Bayleaf Bank wanted to repossess Rebecca's house.

Rebecca now comes to you for advice on whether she has any remedies for undue influence against Olamide (for the 1,000 gift) and Bayleaf Bank (for the mortgage guarantee). Answer the question in IRAC method.
